10.5. Timed-PIV (Particle Image Velocimetry) (JAI Custom)
The Particle Image Velocimetry mode can be used in applications where 2 images
must 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 98.05ms. Then, the second
exposure will be taken. The accumulation is LVAL asynchronous. The first strobe
is activated in the first exposure duration and the second strobe is taken during the
first frame being readout. In this way, two strobe pulses produce two video outputs.
To use this mode:
Acquisition Mode
: Multi (note)
Acquisition Frame Count
: 2 or even number (Note)
Trigger selector
: Frame Start
Trigger mode
: ON
Exposure mode
: Timed
Trigger option (JAI Custom Control)
: PIV
Note: These two features are exclusively set to “Multi” and “2” , if they are set to
others.
In this mode, Trigger Overlap is automatically set to OFF.
