Image Persistence and Reciprocity Failure in HgCdTe Detectors


We present initial findings about the behavior of image persistence and reciprocity failure in HgCdTe infrared detectors. To study these behaviors we developed a new method of measuring reciprocity failure and persistence simultaneously using a 'filmstrip' of sequential, non-destructive reads of the detector. This method not only reduces the number of images and amount of time it takes to measure reciprocity failure but also eliminates the need for ultra-precise lamp calibrations. Our new experimental setup paves the way for future experiments to study persistence and reciprocity failure's link to charge trapping and to further characterize their behavior.
