•
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 checkbox for PIV mode
•
The R29 can be 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 between 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 be controlled by using the „Shtr.“ value in
RxLive to adjust the shutter time
•
The exposure time of the second frame is fixed and can not be controlled in any way
•
A timing diagram is shown in the next picture:
•
The exposure (amount of light contributing to the image) should be controlled by
using a very short pulse of light
•
This can be generated with either a flash or a pulsed laser
•
The camera system should be set up in a dark environment, so that the exposure is
only defined by the light impulse
•
The maximum triggering frequency is reduced to below 3 Hz, because no more than
5.9 frames can be transmitted by the sensor
