Paper Abstract

Persistence or image memory is a common problem in infrared array detectors. In WIRCam, the wide-field infrared camera at the Canada France Hawaii Telescope, two of the four Hawaii-2RG (H2RG) HgCdTe imaging arrays in its mosaic exhibit strong persistence while the other two do not. The dependence of the persistence on illumination flux and fluence has been investigated and the persistence measured on the timescale of hundreds of milliseconds to several hours. The goal of this work is to eventually provide an empirical model to correct for the persistence in image post-processing.
