TRIGGERING
SDK SECTION 5
Page 54
External Exposure
The External Exposure trigger is a mode of operation where the exposure time is fully controlled by the
external trigger input. While the trigger input is high the CCD is accumulating charge in the Image area.
When the external trigger goes low, the accumulated charge is quickly shifted into the Storage area and then
read out in the normal manner. The figures below illustrate the timing sequences for this mode of operation.
