User Manual dolphicam2

Introduction

Congratulation and thank you for getting the dolphicam2! This document is the user manual for the dolphicam2 ultrasound camera platform. The dolphicam2 ultrasound NDT platform consists of a Black Box (BB) and a wide range of Transducer Modules (TRM) with different frequencies and coupling materials. dolphicam2 is delivered integrated with a Panasonic Toughpad FZ-G1 where the Black Box is attached to Toughpad by an x-frame.
We appreciate your feedback on the user manual, so you find that you are missing any information, or anything is unclear in the user manual, please contact dolphitech support.

Please Read Before Use

Please read this page and section “Important Safety Information” carefully before using your dolphicam2!

Intended Use

Dolphicam2 is designed for non-destructive testing of materials.

WARNING

DO NOT use dolphicam2 for any purpose other than its intended use.

In particular, DO NOT use dolphicam2 to inspect or examine human or animal body parts!

Transducer Technology

The dolphicam2 platform has a transducer with 128 transmitting electrodes x 128 receiving electrodes creating a 2D array of 16384 elements over the 32×32 mm transducer (16 elements/mm2), capable of detecting very small defects. dolphitech delivers transducers with different frequency and coupling material (delay line). View the chapter about Transducer Modules to see what we can offer.
The transmitting electrodes cross the receiving electrodes in a 90° angle. In between the transmitting and receiving electrodes, there is a piezoelectric material that generates the ultrasound.

To collect a pulse-echo-signal from a transducer element, a 70V pulse is excited on the transmitting electrode creating a sound field along the entire transmitting electrode, hence across all the receiver electrodes. The ultrasound goes through coupling and/or material and the reflected pulse is sampled on only one receiver electrode. Hence, the sampled pulse only represents one transducer element, which is the cross between the transmitting and receiving electrode.

Ultrasound Visualization

An ultrasound visualization image is based on ultrasound reflections. The figure below shows an illustration of ultrasound reflections with a dolphicam2 transducer module. The dolphicam2 transducer has 16384 transducer elements. Each element works as a speaker and microphone. When a transducer element sends ultrasound, it travels through the coupling medium and into the material to be inspected.

Whenever the sound meets a material with different impedance, the sound is reflected. The different acoustic impedance in the materials influences how much is reflected.

The most common damage/void can be air, where typically more than 99% of the sound wave is reflected. The figure shows two reflection cases, where one has a reflection from the back wall of material and one where the reflection is from a void. Both cases have a penetration echo that occurs between the coupling medium and NDT material.

In the back-wall reflection case, you can see that the reflection comes later, but in the void reflection, the reflection is earlier. The amplitude of the reflections depends on sound attenuation in material as well as distance travelled for the sound beam.

How IS A-scan PERFORMED

Each transducer element gets an electronic signal that is digitalized and represented in an A-scan.

How IS B-scan PERFORMED

B-scan is created by many A-scans put next to each other represented by 1D-Array of transducer elements and shows you a cross section of the material you are inspecting. The B-scan is generated using a color scale, where high amplitude values are given one end of the color scale. In image below, you can see a B-scan where high amplitude values have the color white, and lower amplitude values are dark. In a B-scan you can view the depth of the reflections, hence the depth of voids or damages.

How IS C-scan PERFORMED

The C-scan amplitude image is created from the maximum amplitude of all the B-scans in from your transducer and gives you a view of looking directly into your material from the inspection side. For dolphicam2, you can imagine that your picture is based on the maximum amplitude value of 128×128 A-scans (16384). Each amplitude value is given colour from a colour scale.

C-scan Time-Of-Flight

The C-scan time-of-flight image is created from the time-of-flight value of the maximum amplitude of the A-scans from your transducer and gives you a view of looking directly into your material from the inspection side. The colours of the image show you the depth of the reflection or void. As with the amplitude C-scan, you can imagine that your picture is based on the time-of-flight value of the maximum amplitude of 128×128 A-scans (16384). Each time-of-flight value is given colour from a colour scale.

3D Image

The 3D images are based on the time-of-flight values but can be presented both as 3D amplitude image or 3D time-of-flight image. The 3D image gives you an excellent visualization of your damage.

A green dot on the transducer module (TRM) icon, indicates that the TRM is booted and connected to the BB.

Views

dolphicam2 user interface has many different views that enable you to show only the ultrasound images/visualisations you need. This gives you flexibility at the same time as you can simplify your view for a certain inspection.

ABC (T)

This view shows A-scan, horizontal B-Scan, vertical B-scan and C-scan time-of-flight.

ABC (A)

This view shows A-scan, horizontal B-Scan, vertical B-scan and C-scan amplitude.

All

This view shows all possible ultrasound images: A-scan, B-scan horizontal/vertical, C-scan amplitude and C scan time-of-flight, as well as a 3D view which you can choose from amplitude or time-of-flight. Whenever using this view, we recommend expanding to get large enough images.

This is done by clicking the expand button in the top-right corner of GUI.

The settings menus are then hidden.

B (V) B-Scan Vertical Only

This view shows the B-scan Vertical only.

B (H) B-scan Horizontal Only

This view shows the B-scan horizontal only.

C (T)

This view shows the C-scan time-of-flight. There is also an A-scan view at the bottom which enables you to do gating by clicking/touching directly in the A-scan. Gating is described in another chapter.

C-Scan AMplitUDE | C (A)

This view shows the C-scan amplitude. There is also an A-scan view at the bottom which enables you to do gating by clicking/touching directly in the A-scan. Gating is described in another chapter.

3D Time of Flight (TOF)

This view shows the 3D image based on the time-of-flight values. You can select between 3D displayed in amplitude colors, or time-of-flight colors.

3D Amplitude (AMP)

This view shows the 3D image based on the amplitude values. 3D can also be displayed in time-of-flight colours.

C-SCan Time Of Flight and Amplitude (T + A)

This view shows both the C-scan amplitude and C-scan time-of-flight. Also here there are A-scans under the C-scan to enable gating by clicking/touching directly in the A-scan. Gating is described in another chapter.

Stitch

This view shows the ultrasound image of a larger stitched area. Select what kind of stitching you wish to perform. And adjust settings and control for the stitching. Read more about stitching.

Color Scale and Focus

The colour scales show you the colours used in the C-scans. For C-scan amplitude, the colour is spread out from 0-100%. For C-scan time-of-flight, the colour is spread out on the depth of your scan (selected under coverage). By default, the colours in colour palette are spread evenly over 0-100% in Amplitude images (C-scan and B-scan), and over the complete depth in time-of-flight images.

By using the colour focus sliders in the top and bottom of the colour scale, it is possible to compress the colour scale over a selected amplitude span or depth-span. This is a very good technique to get clearer contrasts in your images if your reflected pulses are less than 100% of the dynamic amplitude range, or if the depth of your scan is larger than detected reflections. The combination of a certain colour palette and colour focusing can help you extract certain damages/defects in your inspected material.

After creating the report, the image and settings list is cleared, ready for a new report.
The report is very basic and works as a container for all the data saved during your inspection. You need to fill in your own text and inspection specific data. All measurements done during an inspection are visible in the respective screenshots.

Example Report

Scan TRM | Activate TRM

The GUI scan button does the same thing as the physical button on your transducer module (TRM). It makes it easy to operate the TRM from the Software in cases you are not holding the TRM. The physical scan button and the GUI scan button works smoothly together, so you can start a scan with one of them, and stop with the other.

Expand View | FUll-screen View

The expand button simply hides the top menu and settings menu and expands the ultrasound images. The different views and the function/measurement buttons are still available. To disable expanded view, click/touch on the same button (arrow in button has changed direction).

Expanded View:

Measure Buttons

dolphicam2 software comes with several measurement tools for both B-scan and c-scans. Each measurement button will hide any other active measurements, except for the Reticle measure button which can be activated independently of other measurements.

Disable Measurement

Adjust the position of B-scan inside C-scan

You can choose where in the C-scan you want the B-scan cross sections by clicking/touching (moving) the cross-hair inside C-scan.

Click the disable measurement button
When the button is black
You may adjust horizontal and vertical cross-section for B-scan (as shown in the illustration)

The disable measurement button turns off all measurements and enables you to set your B-scan crosshair inside C-scan, and enables you to change gating in the B-scan Vertical by clicking/touching inside the B-scan. View Gate chapter for functionality description of gating.

Rectangular Measurement Tool

Rectangular measurement button puts a rectangle overlay on the C-scan. The rectangle can be moved by click/touch-hold-drag inside the rectangle, and you can change the size by click/touch-hold-drag on the edges or in the corner. Rectangle measurement numbers show up on the right side under measurement buttons.

The measurement panel for rectangular measure tool contains the size and dimensions of the rectangle drawn over the C scan. Fine adjustments to the dimensions of the rectangle can be made using Width and Height controls in the panel.

Rectangle measurements:

• Width
• Height
• Area

Circular Measurement Tool

Circular measurement button puts a circular overlay on the C-scan. The circle can be moved by click/touch-hold-drag inside the circle, and you can change the size by click/touch-hold-drag on the edge of the circle. Circular measurement parameters show up on the right side under measurement buttons.
Circular measurements:
• Diameter
• Circumference
• Area

Drill Hole Measurement Tool

When the user selects a drilled hole measure tool, the measurement panel displays the damage size, drill hole dimension and circumferential damage of the drill hole. The drilled hole dimension and the circumferential damage can be adjusted using both the measurement panel and touch-hold-drag over the drill hole tool in the C Scan. The measure tool can be set into the position of the drilled hole by using the control circle.

Line Measurement Tool

Line measurement button enables you to put line overlays on the C-scan and B-scan. You apply the length by click/touch-hold-drag. The line in C-scan shows you the length and can be moved in any direction, while the line in B-scans only can be moved vertically or horizontally, and shows you the depth and/or width of what you are measuring.

Linear measurement:

• Length
• Depth

C-scan measure points

C-Scan measure points button enables you to put up to 10 individual markers in your C-scan image to measure the depth in mm/inches/mils and amplitude in % at each point. You add a point by touching/click anywhere in the c-scan. Then you can move that point around by touch/click and hold and drag. You can remove the marker by touch/click on the marker without holding. The measurement values of the depth and amplitude correspond to the colour values of the C-scan and will change depending the gating and thresholding applied. That means that we measure the distance and amplitude of the point that has the highest amplitude within the current gate(s) that’s above the threshold for that gate (see the chapter on gates and thresholds). The depth measurements will also change if you change the delay parameter (see the chapter on delay)

C-Scan measure point:

• Depth
• Amplitude

C-scan Focus measure point

The C-scan focus measure point allows you to toggle on and off measurements for the current C-scan focus (cross-hair) position. This measure point can be applied independently of all other measure buttons.

C-Scan Focus measure point:
• Depth
• Amplitude

Full Matrix Capture

When pushing the scan button (hardware or software) to stop scanning, a full matrix data set of the last frame is sent from the Black-Box to the computer. This means that you can select B-scans and A-scans using the C-scan focus tool, create new C-scans by adjusting gates and thresholds, adjust depth (from zero to the depth of the captured data set), and change colour focus and colour palettes on the frozen image on the screen. It is also possible to save this data set and its current settings to file, as described in section 8.4.4.

overview Settings for INSPEction:

All the settings for inspections are group into 5 main menus:

Transducer
Coverage
Signal Image
Userprefences
TRM Calibration
Stitching

Transducer menu

The Transducer menu contains settings for Pulse Length, Gain and TCG, Transmitting Elements and Average.

Gain AND TCG

Analog Gain AND Time Corrected Gain

Setting

Input

Gain (Analog Gain)

-40dB to 0dB

Max gain is 0dB

TCG (Time Corrected Gain)

0 dB/µs to 10 dB/ µs

TCG is enabled by GUI button click/touch

TCG will stop at 0dB gain.

Gain increases the amplitude of your signal, but also the noise level. The analogue gain and the Time Corrected Gain can be set using this menu and adjusts gain in the analogue front-end electronics in TRM. If the TCG option is disabled, the analogue gain controls the gain for the whole duration of the A-scan. If the TCG option is enabled, the gain can be increased during the A-scan with a slope that can be adjusted with the input controls. The TCG range is from 0 dB/µs to 10.0 dB/µs. If the total gain (analogue + TCG) reaches more than 0 dB during the A-scan/B-scan depth, the gain will remain at 0 dB for the remaining part of the A-scan/B-scan.

By clicking on the detailed button, the TCG slope of the A-Scan can be adjusted by adjusting the blue points on the A-Scan signal in the Detailed TCG window. The TCG gain level of individual points is visible on the top of the detailed window. The number of TCG points on the detailed TCG window can be increased/decreased using the resolution control. The TCG window can be docked and undocked on your tough pad screen.

Tx ElemEnts(Aperture)

Setting	Input
TX ELEMENTS(APERTURE)	1, 2, 4, 8, 16, or 32

This controls how many transmitting electrodes that are active for each of the 128 transmitting lines. The available values are [1, 2, 4, 8, 16 and 32] active electrodes. A higher number of electrodes gives a higher energy ultrasound pulse than a lower number of electrodes. Transmitting on more than several electrodes creates a focused area under the centre of the electrodes where the ultrasound energy is higher in the middle at a certain depth-range. Transmitting on many electrodes (16, 32) will create a wider beam in the near field where your C-scan image might stretch out the object in one direction. Increasing transmitting elements is a great way to increase signal amplitude without increasing noise. Hence, increasing signal-to-noise-ratio (SNR).

Example of 4 Transmitting elements:

SIGNAL Averaging

Setting	Input
Average	1, 2, 4, 8, 16, or 32

This setting controls how many times the signal pulse for each transducer element is averaged. Hence, how many times you shoot a pulse, record signal, and add them together. The transducer module will transmit and record the set number of times for each element, and the result will be the average from these data sets. A higher number of signal averaging will result in lower noise levels, but also fewer frames per second.

Transducer Pitch

The pitch of a transducer is the spacing between the centres of the individual elements. The default pitch between two transducer elements is 0.25mm. By changing the pitch neighbouring elements are grouped together resulting in larger transducer elements, which will give more penetration into the sample along with an increased frame rate. This functionality is useful to view composite materials such as GFRP (Glass Fiber).

Pulse length

Setting

Input

Pulse Length

5,00ns – 630ns

Resolution is 1/200MHz (5,00 ns)

This setting controls the length of the high voltage pulse that goes into the transducer and generates the ultrasound. The setting has a range from 5,00 ns to 630 ns. Each transducer type has an optimal input pulse to obtain a wide frequency range with high amplitude. Therefore the system detects the TRM type (example TRM-BA-2.25MHz) and sets this optimal input pulse. However, the pulse length can be modified to manipulate the signal and frequency content of the ultrasound. The pulse has a certain rise-time and fall-time which depends on the load of the transducer. Typically rise/fall time is around 6-9ns.

Illustration pulse lenght:

Coverage menu

The Coverage menu has the settings for Delay, Depth, Velocity, Gate, Capture Method.

Delay

Setting	Input
Delay	1.00µs – 81.90µs

Delay is the time between the start of the transmitting pulse and the start of the sampling of data. This will typically be set to a fixed value for each transducer type, depending on the type and thickness of the coupling pad. Delay can be adjusted so that your penetration echo (echo between coupling and material for inspection) occurs at 0mm. Other cases where you want to adjust delay is when you use a coupling shoe/wedge or water-box.

Range

Setting	Input
Range	0mm – 126mm (velocity-dependent)

This setting controls the depth of your inspection, hence how long each A-scan/B-scan will be and the depth in which your C-scan is created from. The default depth is set according to what transducer type you have as the thickness of your coupling sets when your second echo from coupling occurs.

Velocity

Setting	Input
Velocity	Manual (100m/s – 20000m/s) Pre-configured speed list: Aluminium, 6320 Brass, 4280 Copper, 4600 CFRP (Carbon Fiber), 3070 GFRP (Glass Fiber), 2740 Glass, 4540

This setting adjusts the velocity in the material to inspect and influences the depth scales and measurements in the Software. The value can either be set manually by clicking/touching or writing the correct value or can be selected from a pre-defined list of know material with the corresponding Velocity.

Gates/Threshold

A C-scan image is based on the maximum values from all the 16834 A-scans. The depth of your inspection is set in Depth setting. Within this depth, the start gate and end gate set the depth range of which the maximum amplitude values are selected for creating the C-scan image.

The easiest way to set the start gate and end gate is to click/touch/touch directly in the B-scan Vertical image.
If you want more accurate control of the gating, you can adjust the settings at the bottom right.

The amplitude C-scan and time-of-flight C-scan has separate gating which is chosen by clicking/touching/touching the “Amp Gate” or “ToF Gate” button.
There is also a lock button that locks the relative distance between start gate and end gate and you can move this locked range up and down in depth by adjusting Start. You can change the width of the gate by adjusting width up and down.

Threshold

In addition to gates, it is possible to adjust the amplitude threshold for the creation of C-scans. This means that only A-scan values that are above the threshold value within the gate are selected for C-scan creation. The threshold can be adjusted by touching/clicking in the A-Scan view of C(T), C(A) and full views. Dragging the threshold line up (or up/down if A-Scan mode is full) applies the threshold. For fine adjustments, use the threshold control in the Gates/Threshold settings.

Multiple Gates

It is possible to select up to three individual gates for both amplitude and time of flight c-scan. Each gate has its own individual threshold that works only within the range of that gate.

To select more gates, you must select the gate settings (be sure that you are in the Inspection Tab, select Coverage Menu and Gates/Threshold menu item.

First select number of gates (1, 2 or 3) in the “Gates” option.

To adjust the individual gates or thresholds. Select the appropriate gate number in the “Select Gate” option.
Each gate can be locked, as previously described.

The figure below identifies the various gates and thresholds.

Gates/Threshold DURING FMC

When the system is in FMC data mode, either after stopping the scan, or loading from file, gate and threshold values are not updated continuously, as opposed to streaming live data. In the B-scan and A-scan views, the values are only updated on touch release/mouse button release. When adjusting gates and thresholds using the gate/threshold setting window, the changes are applied in approximately 1-second intervals. This is to avoid that the system becomes unresponsive due to the size of the data that needs to be processed by the computer CPU.

Transducer AREA

The user can change the area of a scan of the transducer in order to get a closer view of the sample being examined along with an increased framerate. For example, while inspecting drill holes in carbon fibre, it gives a closer view of the drill hole and the delamination area. There is a set of predefined transducer area that can be selected depending upon the required inspection area for the examination.

Capture method

Setting

Input

Capture Method

Maximum Absolute Value

Maximum Positive Value

Maximum Negative Value

Capture Method controls whether C-scan is generated on maximum absolute value (max negative or positive), maximum negative value or maximum positive value. In many cases, the pulse is symmetric around zero, in which case the maximum positive and maximum negative value are the practically the same. This results that some cases that it is coincidental will choose between maximum negative versus positive. This causes inaccuracy in time-of-flight. In this case, it is better to choose either maximum positive or maximum negative value. In cases you know which polarity of your reflected signal is superior, you should select the corresponding capture method.

Signal and image

Under Signal & Image you can find the settings for; A/B Scan Mode, Color Palettes, and Image Filter.

A/B scan mode

Setting	Input
A-Scan Mode	Full signal Absolute value of the signal Envelope of the signal
B-Scan Mode	Full signal Absolute value of the signal Envelope of the signal

This setting selects how the A- and B-scans are presented in the GUI. There are three ways of displaying the A-scan and B-scan; Full, Absolute and Envelope.

Full mode

Full mode displays the signal as it is. This gives you a detailed view and understanding in A-scan where the signal is symmetric around 0 %. This mode does not make as much sense in B-scan.

Absolute mode

The absolute mode takes the absolute value of the signal, hence there are no negative values. This still gives you some details of the signal behaviour.

Envelope mode

Envelope mode lays an envelope over the absolute maximum signal. This makes the interpretation in A-scan and B-scan easier.

Colour palettes

Setting

Input

Color Palettes:

C-scan Amplitude & B-scan
C-scan Time-Of-Fligth

Jet
Gray
Gray Inverse
Autumn
Bone
Winter
Rainbow
Ocean
Summer
Spring
HSV
Pink
Hot

This setting selects which colour palette to use in C-scan and B-scan Amplitude C-scan and B-scans share one palette, and ToF-C-scan has a separate palette. Which palette you adjust is controlled by clicking/touching the Amplitude or ToF button in Color Palettes menu.

Digital FIR filter

Digital filters are widely used in signal processing to remove or to keep certain components of the signal. The LPF allows the low frequency to pass and filters out the high frequency; in other words, all portions of the signal that change rapidly are filtered, such as noise. The scaling factor is used to scale the cutoff frequency of the filter. LPF smoothens out the rapid changes in the intensity of the pixels in an image. The low-pass filter affects the noise more than it does the image. By suppressing the noise, gradual changes can be seen that were invisible before. Therefore, a low-pass filter can sometimes be used to bring out faint details that were smothered by noise.
In dolphicam, we have different low pass filters for transducers with an adjustable scaling factor. We have low pass filters with cut off frequency ranging from 0.5 MHz to 11MHz. The default scaling factor is set to 1 for all low pass filters, that can be adjusted with the controls on the user interface.

Image filter

Setting	Input
Image Filter (C-scan Amp & ToF)	None Gaussian Median

Image Filter can be applied to both C-scan Amplitude and C-scan Time-Of-Flight. These are basic image processing filters from OpenCV.

Gaussian filter

Gaussian filter smoothens the image and reduces noise. Gaussian filtering is done by convolving each point in the input array with a Gaussian kernel and then summing them all to produce the output array.

Median filter

The median filter runs through each element of the signal and replace each pixel with the median of its neighbouring pixels.

Filters compared

TRM Calibration / NOrmalization

If your Transducer Module has not been used with your Toughpad (or PC) before, a system normalization is necessary. It is also a good habit to normalise the system before each new inspection. Normalization only takes a few seconds. This normalizes for amplitude variations between all 16384 elements in transducer as well as time-of-flight variations due to minor thickness variation in coupling pad.

If your TRM has not been calibrated on the Toughpad you are using, the Software will prompt a normalization.

Calibration only takes a few seconds. The calibration calibrates for amplitude variations between all 16384 elements in transducer as well as time-of-flight variations due to minor thickness variation in the coupling pad.
If your TRM has not been calibrated on the Toughpad you are using, the Software will prompt a calibration.

A calibration window is opened that tells you some important information before calibration:
• Make sure the transducer front is clean
• Point TRM front towards air
• Push the Calibrate TRM button

After this very first normalization, the normalization is done in the SETTINGS window under TRM Normalization menu . The normalization procedure is described in the TRM Normalization menu window. You can turn ON/OFF the normalization switch button and then click on Start normalization button at the bottom of the menu. Turning OFF the normalization button might be useful for R&D applications, but we recommend to never turning normalization OFF during NDT measurements.

The Normalization procedure is the same as described in the TRM Calibration menu window.

You can also disable both Time-of-Flight Calibration and/or Amplitude Calibration by clicking/touching the “Time of Flight Calibration/Amplitude Calibration” buttons. Disabling calibration might be useful for R&D applications, but we recommend to never disable calibration during NDT measurements.

User Preference

Under User Preferences, you can adjust settings for Measurement Unit.

Setting	Input
Measurement Unit	Millimeters Inches Mills

Measurement units are just to set your preference of what unit you want scales and measurements should be displayed in.

Stitching

Stitching configuration segment has the configurations; Two and One Axis Encoder Stitching, Manual Stitching, GridTool Stitching. The stitching functionality is to easily create ultrasound images that are larger than the transducer front end.

Note: The image filter is set to none, when using stitching mode. It can be manually reset to preferred image filter type if needed, but it will cause the corners of the image to be cut off. The image filter will revert to default/selected type when changed to other views.

Manual Stitching

Visual reference	Setting	Input
	Height of your stitched image	Min: 32mm Max: 506mm
	Width of your stitched image	Min: 32mm Max: 506mm
	A pattern for your stitching (how to move you TRM)
	Camera rotation in reference to dolphicam2 GUI
	Shortcut roll-down for pre-set stitching sizes	106 x 106 mm 206 x 206 mm 306 x 306 mm 406 x 406 mm 506 x 506 mm
	Overlap between the stitched C-scan (tiles). Number in parenthesis shows the distance from center-to-center of each C-scan (tile). This number can help you set a grid for your material inspection.	Min: -5mm Max: +15mm
	Clear Canvas	Button Click/Touch
	Pop out active C-scan	Button Click/Touch
	Switch between C-scan Time-of-Flight and Amplitude	Button Click/Touch
	Zoom in/out in stitched canvas view	Button Click/Touch

When inspecting a large predefined area, the easiest way of using manual stitching is to follow the scanning sequence that you set up. Just follow the numbering and active tile (red blinking frame) during your stitching. Click the dolphicam scan button to start scanning, when you are satisfied with your image (good coupling) click to freeze the tile and the active tile moves to next number in your scanning sequence. Repeat this until your entire stitched area is completed.

Step by step Manual Stitching

Set the size of your area you will stitch, in one of the following ways:
- Select a pre-defined area in roll-down menu «Inspection Area»
- Adjust “Height” and “Width” using the +/- buttons.
- Click on the green arrows in the outline of your stitch area.
Set «Tiles in View» to get a full overview over stitch area.
Select the “Stitch Pattern” you want to do the stitch with.
Set “Camera Rotation” according to how the camera is in reference to the Software GUI.
Set the “Stitching Overlap” you have decided (default 6mm).
Activate Pop-out window if desired (if stitch area is large, it is nice to see the enlarged pop-out).

The stitch sequence will be displayed for you. Whenever you click to freeze your C-scan image, the image moves to the next tile in your stitch.
To reset your stitching canvas, click/touch the clear canvas button. All your tiles will then be deleted, and scanning sequence is started over.

Each tile in the stitch is as big as the transducer front (32x32mm). The tiles overlap by 7mm (default), which means that the tiles (centre-to-centre) are 25mm apart. The stitching overlap can be adjusted in stitching window. The camera should be oriented in the same angle for each image taken (this is relatively easy). If your C-scan images are not perfectly aligned, simply move them around with click/tough-and-draw. You can also control the overlap on images by right-clicking (tough-and-hold) and selecting “Bring to front”, or “Send to back” (view the bottom image below).

Manual Stitching Tip

If you set your stitch overlap to 25mm (~1 inch) apart, you can prepare your measurement by marking your material for inspection with dots 25mm (~1 inch) apart in all directions, either by using a ruler or e.g. a silicon sheet with pre-cut holes in it. Using these predefined marks, you can easily aim at them using one of the lines in dolphicam housing. Doing this really simplifies and speed up your inspection.

Grid Tool Stitching

The dolphicam Grid Tool is a mechanical position device for the TRM that makes it easy and quick to inspect large areas. How to set up the Grid Tool is described in a separate manual.

The Grid Tool stitching in GUI works exactly like manual stitching, except that the overlap is fixed to 7mm so that each tile covers 25mm. Setup the stitching the same way as described in the manual stitching chapter. For each C-scan tile, click the TRM button to freeze the image, and the C-scan tile automatically moves to the next tile. Release the Grid Tool locking mechanism and move to the next tile according to your stitching pattern.

One axis Encoder Stitching

dolphicam2 is compatible with any common quadrature encoder systems like the ODI from JIREH, and the C-Clamp from Phoenix ISL.

The Encoder Stitching GUI is very much like the manual stitching GUI and Grid Tool stitching GUI.

Button/Referance	Setting	Input
	Area of transducer used in stitching	2.5 x 25mm 5 x 25mm 10 x 25mm 25 x 2.5mm 25 x 5 mm 25 x 10mm
	Camera rotation in reference to dolphicam2 GUI
	Encoder type (sets counts/mm automatically)	ODI (16) C-Clamp (32,8) Raster (200)
	Counts per millimetre	Minimum: 1 counts/mm Maximum: 300 counts/mm
	The pattern for your stitching (how to move you TRM)
	Sets direction that GUI interprets encoder direction	Click / Touch
	Sets which stitch lane you are operating	Minimum: 1 Maximum: 50
	Shows where in stitched canvas encoder/TRM is located	Displayed
	Clear Canvas	Button Click/Touch
	Pop out active C-scan	Button Click/Touch
	Switch between C-scan Time-of-Flight and Amplitude	Button Click/Touch
	Zoom in/out in stitched canvas view	Button Click/Touch

Start by mounting the encoder system to the dolphicam2 TRM. If you use encoders like the ODI for JIREH, mark the stitching pattern you plan to do on your sample. Apply water or gel (or mixture) to allow smooth movement of TRM coupling. Follow the marked lines with TRM rolling the encoder wheel behind your TRM. For each lane, click the TRM scan button to freeze the image, and move over to the next lane. The Software GUI will automatically move C-scan to the next tile. This can be overridden if you need to redo any of the lanes. A good idea to get this stable is to put a long edge (like a ruler) along the marked line so the TRM can follow this edge.

TWO axis Encoder Stitching

This feature allows for movement of the encoder in both X and Y axis at the same time which makes the stitching more efficient for large surfaces.

Accessories

Ultrasound Gel & Water

dolphiTech recommends using water or ultrasound gel or a mixture of gel and water to obtain good acoustic coupling between the transducer coupling and the material for testing. Water can be applied by a spray bottle. Mixing a small amount of gel in your water spray bottle creates a nice smooth stickiness that keeps the coupling material on the desired area.
An example ultrasound gel we recommend is ECO SUPERGEL. This gel is not hazardous or flammable and is safe to use. We also recommend mixing a small amount of water in your gel in a separate bottle to make a gel that is more liquidly. Typically, ultrasound gel on the market is not hazardous or flammable in any way and is safe to use.

Teflon Tape – Corner Pieces

Teflon tape is a very good material to either protect the coupling by covering the transducer front with Teflon tape or as corner distance pieces to enable the transducer module to slide easily while scanning. Contact dolphitech sales for Teflon tape recommendation or corner pieces.

Encoders AND STITCHING

Grid Tool

Grid tool is a dolphitech product for easy manual-mechanical stitching with both dolphicam1 and dolphicam2. Please contact dolphitech sales for a quote. The Grid Tool does not require any connection to the dolphicam2 system – the Software GUI easily sets up the stitching with Grid Tool (view stitching chapter under Software & Functionality).

Encoders x And Y tool

dolphicam2 has two encoder inputs and are compatible with quadrature encoder solutions. The connectors have screws on the side to safely secure the encoder connection.

Two recommended encoders that work well with dolphicam2 and can be ordered with Dolphcam2 connector are C-Clamp (Phoenix ISL) and ODI (JIREH). The Software GUI easily sets up the stitching with encoders (view stitching chapter under Software & Functionality).

We recommend keeping the dolphicam2 system (both TRM and BB) clean for longer durability and to avoid system failure. All necessary cleaning and maintenance are described in this chapter.

Cleaning TRM & BB

We recommend cleaning BB and TRM housing if it is exposed to anything that may cause stains—such as dust, dirt, ink, paint or oil. Turn Off the BB and TRM as well as Toughpad and disconnect it from the Toughpad or PC. It is not necessary to disassemble the BB from Toughpad. Wipe it off/clean it with a soft, lint-free cloth moistened with mild soap water. Do not use solvents of any kind. Avoid getting dirt into openings. Don’t use aggressive cleaning products or compressed air.

Use air spray to remove dust and contamination from connectors and heat sinks on both BB and TRM. Connectors that are not in use should be covered with plastic caps that follows the BB system.

Cleaning the Transducer Front

Disconnect the TRM from the BB. Put a drop of mild dishwasher soap on the transducer pad and rub it gently with the tip of your finger. Dip your finger in water and rub on pad until soap is gone. Make sure the Transducer Pad isn’t scratched or damaged. Moist a soft, lint-free cloth with water and wipe off excessive water carefully.
