Laboratory Measurement of the Brighter-fatter Effect in an H2RG Infrared Detector
Laboratory Measurement of the Brighter-fatter Effect in an H2RG Infrared Detector
The "brighter-fatter" (BF) effect is a phenomenon—originally discovered in charge coupled devices—in which the size of the detector point-spread function (PSF) increases with brightness. We present, for the first time, laboratory measurements demonstrating the existence of the effect in a Hawaii-2RG HgCdTe near-infrared (NIR) detector. We use JPL's Precision Projector …
