3.5.3 - Trigger options in Fast Kinetics (FK) mode
3.5.3.1 - Internal (FK)
As Fast Kinetics uses both the Image and Storage areas as temporary storage areas, the number of options available
is quite limited. The simplest mode is again Internal Trigger and, as with the internal trigger modes described previously,
the system determines when the acquisition begins and then uses the exposure time dened by the user. On completion
of the exposure period the camera performs the number of vertical shifts dened by the user, and then again waits for
the exposure period before the next set of vertical shifts.
This process is repeated until the number in the series is captured, at which point the readout starts. The timing
sequence is shown below and as before the Fire output envelopes the period when no vertical clocking is occurring.
There are no readout cycles or Keep Clean Cycles running during the sequence, hence the very fast kinetic cycle period
but limited number of exposures in the series.
