10.3.5 High S/N mode
In this mode, each sensor output is synchronized and has the same exposure time. The image
average of the two signals is the output. The shutter and trigger settings for BW1 are applied to
BW2. The same video output is fed through GigE-1 and GigE-2 and can be captured by setting
the appropriate port.

10.3.6 PIV ( Particle Image Velocimetry ) mode
The AD-081GE has a PIV (Particle Image Velocimetry) mode. This mode provides three (3)
consecutive images by one trigger pulse. When the trigger is input, the first exposure on BW1
can be captured, followed quickly by an exposure on BW2. After the exposure on BW2 is
completed, a second exposure on BW1 is made. Each exposure is executed by a strobe flash in
very short interval period. The exposure time is preset at 4 µs, 6µs or 8µs by registers.
