7.8. PIV (Particle Image Velocimetry)
The Particle Image Velocimetry mode can be used in applications where 2 images need to be
taken with a very short time interval. It can only be used with strobe flash as illumination.
The first accumulation time is 10
sec to 2 sec. Then, the second exposure will be taken.
The accumulation is LVAL asynchronous. The first strobe is activated during the first exposure
duration and the second strobe is pulsed while the first frame is being read out. In this way, two
strobe flashes generate two video outputs.
Primary Settings
Exposure Mode: Timed
Trigger Mode: ON
Trigger Option: PIV
In this mode, the setting of Trigger Overlap is invalid.
