Dark Current Measurements on a State of the Art Near-IR HgCdTe 1024x1024 Array . ... We discuss the viability of these methods for determining dark current and the results of the measurements on the device. ... The first method (modified standard method) of estimating the dark current uses the second set of reset frames to correct for the drift that occurs during the exposure. ... The second method (variance method) exploits the fact that the dark current follows Poisson statistics. ...
