Teledyne DALSA
Snapshot Mode
In this mode the detector will initiate a sensor reset at the rising edge of the trigger input
and succeeding to this it will read-out the sensor at the falling edge.
The sensor reset is actually a normal read-out of the sensor but the data is discarded.
The trigger output indicates the Exposure Time when no reset or read-out of the sensor
occurs.
To allow sufficient time for the sensor reset, the delay between rising edge of the trigger
input and when the detector is exposed to x-ray should equal or higher to the reset time
of the sensor (D).
