Appendix A: Exposure Timing Diagrams
Continuous, overlapped exposure mode with electronic shutter
In the continuous, overlapped exposure mode, the camera remains in an idle state until the falling edge
of the trigger. A first exposure is made, followed by the typical, interline CCD overlapped
exposure/readout cycle. Electronic shuttering allows the exposure to be adjusted via software control
without altering the frame rate of the readout. Any further triggers while the camera is operating
continuously are ignored. The camera will remain in this continuous operation until disabled through
software command. It can then be re-armed for another trigger event.
