READOUT MODES
SDK SECTION 3

Cropped
In Cropped mode, we can "fool" the sensor into thinking it is smaller than it actually is, and readout
continuously at a much faster frame rate. The spectral time resolution is dictated by the time taken to readout
the smaller defined section of the sensor.
If your experiment dictates that you need fast time resolution but cannot be constrained by the storage size of
the sensor, then it is possible to readout the EMCCD in a "cropped sensor" mode, as illustrated below.
Figure 7: Cropped mode
To set up the CCD with a cropped image, as in figure 7, see SetIsolatedCropMode.
NOTE: It is important to ensure that no light falls on the excluded region otherwise the
acquired data will be corrupted.
