  • Page 4: Overview

    DolphiCam is an advanced ultrasound camera designed for test and inspection of CFRP (Carbon fiber reinforced plastic) to detect material flaws and defects. The DolphiCam connects to a standard Windows PC or Windows tablet (not included), making it easy to view and interpret results.

  • Page 6: Charging

    Make sure that you do not unintentionally leave the camera in scanning mode, as this will drain the battery. 1.4.4 Charging The DolphiCam is delivered with some power in its internal battery. The camera should be fully charged with the supplied charger before first use.

    Low battery is indicated in the software by a blinking battery symbol above the C-Scan. 1.5 Starting Application Start the DolphiCam software by clicking on the icon on your desktop. Alternatively, start DolphiCam with the name of a DolphiCam configuration file as a parameter: Example: C:\Program Files (x86)\DolphiTech\DolphiCam\DolphiCam.exe <mysettings>.dolphicam You can also double click on the configuration file to start DolphiCam software 1.6 Software Overview...

  • Page 9: Calibrating The Camera

    1.6.1 Calibrating the Camera Before use, the camera must be calibrated. This will ensure that the ultrasound system is adjusted to the small variances in the transducer as an effect of microscopic deformations, temperature variations and other factors. Calibration is performed towards air. The Calibration Wizard starts the first time the camera is connected to the PC: ...

    Amplitude and Time-of-Flight. DolphiCam scans in both Amplitude and Time-of-Flight modes and data is recorded independent of which scan mode the application is in. The user can at any time switch between the two image modes by pressing Amplitude or Time-of-Flight buttons in the application.

  • Page 12: A-Scan

    1.8 A-Scan The A-Scan is presented in the bottom, left part of the application. The A-Scan displays a signal processed time series of the ultrasound reflection from the material at the intersection between the C-Scan crosshairs, over the depth of the material. 1.9 B-Scans The B-Scan represents a cross-section through the material.

  • Page 13: Horizontal B-Scan

    1.9.2 Horizontal B-Scan The horizontal B-Scan is positioned to the right of the A-Scan, and below the C-Scan. The horizontal B-Scan displays a horizontal cross-section at the position of the horizontal line in the C-Scan image. 1.10 3D View Data from the Time-of-Flight scan is used to give a 3D representation of the material and any defects. For each time the 3D button in the main window is pressed, a new 3D image is produced.

  • Page 15: Amplitude Threshold

    1.11.2 Amplitude Threshold The blue horizontal line in the A-Scan sets the amplitude threshold (0-100%). All signal amplitudes below the threshold will be ignored: For C-Scan Amplitude and B-Scan images:  All signal amplitudes below the amplitude threshold will be interpreted as the same value as the threshold value.

  • Page 16: Color Focus

    1.11.3 Color Focus By default, the DolphiCam will spread colors in the palette evenly over 0-100% in Amplitude Images and over the complete depth in TOF image. By using the Color Focus Slide Bar to the right of the C-Scan, it is possible to focus the colors in a smaller part of the color scale.

  • Page 17: Measurement In C-Scan

    1.11.4 Measurement in C-Scan By right-clicking drag-and-hold in the C-Scan, you can measure the size of your defect. This is useful for measuring the size of material defects. 1.11.5 Depth Measurement in B-Scan By right-clicking drag-and-hold in any of the B-scans, you can measure the depth from the click position to the mouse position.

Setting Input Unit Select from dropdown list:  Millimeters (mm) - default  Inches (in)  Mils (1/1000 inches) 1.11.7 Material depth Limits the material thickness to be examined. Sets the depth scales for A-Scan and B-Scan. Also, this affects the color distribution in C-Scan TOF.

  • Page 19: Number Of Averages

    The default number of transmitting elements is 4. Setting Input Transmitting Select from dropdown list:  elements    4 - default  1.11.10 Number of Averages Noise reduction strategy. You can choose how many averages the system runs on each transducer element. A lower number of averages gives you slightly poorer Signal-to-Nose ratio, but a higher frame rate.

  • Page 20: Transmitting Pulse Shape

    1.11.11 Transmitting Pulse Shape DolphiCam has 8 different user selectable transmitting pulse shapes. Each pulse shape has an adapted digital filter. The combination of the nature of the pulse shape and the adapted digital filtering makes each pulse special in the sense of different parameters, such as Signal-to-Noise ratio, pulse length, etc. Each of the different pulse shapes has different qualities that makes them suitable for different material, material thickness, size of defect, etc.
