Shutter/Exposure Timing<br />
Because the Pantera SA <strong>2M30</strong> can be reading out a previous image while shuttering for<br />
the next image there are some timing constrains imposed by the sensor specification on<br />
this timing. The result is that the actual integration time of the camera must be<br />
synchronized to the vertical clocking. The vertical clocks have a period of about 30µs so<br />
this produces an uncertainty window around the desired integration time to what is<br />
generated by the camera. The figure below shows how this uncertainty window is<br />
applied for various operating conditions.<br />
