In multiple trigger {Shift Per Trigger} mode, each exposure-shift cycle is triggered
independently by a pulse applied at the Ext Sync connector. This mode is useful when
each subframe needs to be synchronized with a pulsed external light source such as a
laser.
illustrates the timing diagram.
Figure 6-14: Timing Diagram: Kinetics Mode, Multiple Trigger {Shift Per Trigger}
NOTE:
It is particularly important to keep ambient light to a
minimum while multiple trigger mode is used. In the case of
this mode, automatic cleaning of the CCD only occurs until
the first trigger arrives. Once the series of "exposure-shift"
cycles begins, cleaning does not occur and, at the end of a
cycle, ambient light will be collected through the window
until the next trigger arrives. Depending on the time
between triggers and the amount of ambient light, some
subframes may appear brighter than others.
See
for configuration information.
