3.3.5 - Baseline Optimization

3.3.5.1 - Baseline Clamp

When acquiring data, small changes in the ambient temperature and/or in the heat generation of the driving electronics

within the camera may cause some drift in the baseline level. This is most often observed during long kinetic series. The

iXon Ultra series employs a Baseline Clamp technique that holds the baseline to a predetermined level. Baseline Clamp

corrects each individual image for any baseline drift by subtracting an average bias signal from each image pixel and

then adding a xed count level to ensure that the displayed signal level is always a positive number of counts.

NOTE: Baseline clamp is permanently on during normal operation.
