Software
– the camera expects a computer to send a command to the camera for
generating one short trigger pulse. You can trigger the camera by clicking the GUI
Software Trigger button or by sending the GenICam™ Trigger Software command.
5.10 Strobe and Synchronization Controls
The camera allows you to synchronize your system from several references. You can
synchronize with the trigger input, the start, middle or end of exposure, or the
vertical/horizontal synchronization signals (see
.
1)
The camera provides signals indicating the start of exposure, mid-exposure, and end
of exposure. These signals have a fixed duration of 2 microseconds. These signals can
be delayed using the TriggerDelay feature in the Acquisition Control menu to also
synchronize multiple cameras or light sources. If a longer pulse period is required,
the strobe feature can be used.
2)
The camera also provides a strobe that activate just as the readout period begins and
can be activated on all frames or just even or odd frames . If using internal exposure
control, you can position the strobe to occur when the exposure time starts by using
the strobe delay feature. (The strobe delay should be set to the trigger period minus
the exposure time in Standard trigger mode or Readout period minus exposure time
in Fast trigger mode) You can position each strobe pulse within the entire frame-
timing period with a precision of 1.0 microsecond. You can set the strobe position
and duration from 1.0 microsecond to the maximum frame time with a precision of
1.0 microsecond.
