1. Overview
1.1 General
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.
The camera has a transducer with 124 x 124 (15376) elements over the 31x31 mm transducer (16
elements/mm2), capable of detecting very small defects. The transducer pad is silicone-based, enabling dry
coupling on smooth and painted surfaces. Water or contact gel can be used to improve coupling on rougher
surfaces.
1.2 Visualization
DolphiCam supports the following visualization images:
A-Scan
B-Scans
oB-Scan Horizontal
oB-Scan Vertical
C-Scans

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.
Charge DolphiCam with the included USB cable or power adapter. Using damaged cables or chargers, or
charging when moisture is present, can cause electric shock. Power adapters may become warm during
normal use, and prolonged contact may cause injury. Always allow adequate ventilation around power
adapters when using them.
Charging the DolphiCam to full capacity will take up to 5 hours using the charger.
The charging LED is RED when the camera is charging.
The charging LED is GREEN when the camera is fully charged.
NOTE: The DolphiCam charges whenever the camera is connected to an USB port.
NOTE: Make sure the camera is turned OFF using Off/Mode Switch before charging.
1.4.5 Installing Software
See Installing Software (chapter 4).
1.4.6 Connecting and Starting the Camera
When the software installer has finished, connect the camera to the PC by inserting the USB plug.
Turn the camera ON by setting the Off/Mode Switch to “1”.
It is optional to turn the camera ON before it is connected. If the camera is turned OFF when it is connected,
the application waits until a camera is detected.

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

1.6.1 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:
Point the camera towards air and turn Mode Switch to “Calibrate”.
Click the Scan Button to start scanning.
The calibration sequence will take a few seconds.
Turn Mode Switch back to “1” when the calibration is finished.
Click the Scan Button again to stop scanning.
The camera can be re-calibrated at any time. The calibration is not affected by camera settings.

1.6.2 Taking Images
Click the Scan Button to start scanning video.
Click the Scan Button again to freeze image (stop scanning).
When scanning towards air, the result will be something like this:
