11-2-6 TRIGGER OUTPUT
The camera provides a range of trigger output signals with Lightsheet Readout Mode. The global
exposure timing output is not provided, however, because there is no timing where all lines expose at
the same time with Lightsheet Readout Mode.
It is possible to program and output a pulse that has an optional pulse width and an optional delay time
to Read End (the end of readout timing) and Vsync for programmable timing output. In addition that, it is
also possible to program an optional pulse width and an optional delay time to Hsync for programmable
timing output with Lightsheet Readout Mode.
(1) Programmable timing output
By using the programmable timing output, synchronizing with external devices is simple. A
system which needs simple timing signal does not require a delay unit or pulse generator. It is
possible to program and output a pulse that has an optional pulse width and an optional delay
time to Read End (the end of readout timing), Vsync or Hsync. The range of delay is 0 µs to 10 s,
and the range of pulse width is 1 µs to 10 s.
The relation between the parameter which can be set with each reference signal, and an output
signal becomes as shown below.
Reference signal Output signal
Read End
Camera outputs a pulse after certain delay from the end of sensor readout.
Also the pulse width can be set.
Vsync
Camera outputs a pulse after certain delay from the beginning of readout.
Also the pulse width can be set.
Hsync
Camera outputs a pulse after certain delay from the Hsync which is internal
signal and whose interval time 9.744 36 µs. Also the pulse width can be set.
