Baumer cameras.

Camera in trigger
mode:
A - Trigger delay
B - Exposure time
(global shutter)
B*- Exposure time
(rolling shutter)
C - Readout time
Trigger Delay:
The trigger delay is a
flexible user-defined delay
between the given trigger
impulse and the image cap-
ture. The delay time can
be set between 0.0 μsec
and 2.0 sec with a stepsize
of 1 μsec. In the case of
multiple triggers during the
delay the triggers will be
stored and delayed, too.
The buffer is able to store
up to 512 trigger
signals during the delay.
Your benefits:
▪ No need for a perfect
alignment of an external
trigger sensor
▪ Different objects can be
captured without hardware
changes
