• Click on the teal slider icon to open the additional camera property window
• Set the external trigger mode to „Camera“
• If you wish to use the PIV mode, activate the check ox for PIV mode
• The R29 can e triggered in external trigger mode at up to 5.9 frames per second
• Using a faster trigger impulse frequency will result in lost frames
PIV mode
• In PIV mode, each trigger impulse will capture two images in a very short period of
time
• The delay etween the end of the first frame and the start of the second frame is
approximately 30 microseconds
• The exposure time of the first frame can e controlled y using the „Shtr.“ value in
RxLive to adjust the shutter time
• The exposure time of the second frame is fixed and can not e controlled in any way
• A timing diagram is shown in the next picture:
• The exposure (amount of light contri uting to the image) should e controlled y
using a very short pulse of light
• This can e generated with either a flash or a pulsed laser
• The camera system should e set up in a dark environment, so that the exposure is
only defined y the light impulse
• The maximum triggering frequency is reduced to elow 3 Hz, ecause no more than
5.9 frames can e transmitted y the sensor
