Abstract
Infrared CCD arrays generally require a compensation for the effect of gain and offset variation among the individual detectors of the array. Linear compensation techniques do not suffice for focal planes that exhibit a large nonlinearity of response combined with order-of-magnitude variations in threshold and saturation flux levels. This situation is common among hybrid architecture CCDs, particularly when HgCdTe is the detector material. This paper reports on a multipoint piecewise-linear correction scheme employed on a HgCdTe infrared CCD focal plane. This technique allows a compensated response to be obtained in a computationally efficient manner. An experimental relationship between the number of calibration points and the amount of residual fixed-pattern noise is presented and compared to previous analytical models.
