11-1-7 TRIGGER OUTPUT
The camera provides a range of trigger output signals to synchronize with an external instrument and
the camera becomes the master and the external instrument becomes the slave.
There are three different trigger output functions as follows.
- Global exposure timing output
- Programmable timing output
- Trigger ready output
Also, it can output continuous High output (High output fixed) or continuous Low output (Low output
fixed). They are output from Timing out connector.
(1) Global exposure timing output
It shows the global exposure timing where all lines expose at the same time. There is a case that
one event is divided into two frames because the timing of the exposure in each line is different
for the rolling shutter. However, by using the Global exposure timing output the global exposure
becomes possible for the phenomenon that happens for this period. Global exposure timing
output shows the period where all lines expose at the same time.
Note
•
There is no output signal when the exposure time is less than the frame rate.
(2) Programmable timing output
By using the programmable timing output, synchronizing external devices is simple. A system that
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 Input trigger signal. The setting range for delay time is 0
µs to 10 s, and the setting range for 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 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.
Input trigger signal
Camera outputs a pulse after certain delay, from the input trigger signal.
Also the pulse width can be set.
