8.16 Strobe
The camera can provide a Strobe output signal. The signal goes high when the exposure time for each frame
acquisition begins and goes low when the exposure time ends as shown in the figure below. This signal can be
used as a flash trigger and is also useful when you are operating a system where either the camera or the object
being imaged is movable. Typically, you do not want the camera to move during exposure. You can monitor the
Strobe output signal to know when exposure is taking place and thus know when to avoid moving the camera.

Strobe Offset (VC-25MC/VC-25MC2 Only)
The Strobe Offset value specifies a delay that will be applied between the point where the shutter signal rises
and the point where the Strobe output signal rises. You can set the Strobe Offset in microseconds by using the
“sso” command. The width of Strobe output signal will be the same as the width of exposure but the only the
point where the Strobe output signal rises is adjusted.

Strobe Polarity
The Strobe Polarity is used to select Active High or Active Low triggering. You can set the polarity of the strobe
output signal by using the “ssp" command.
