Abstract

A critical component of IR sensors is the infrared detector. In order to predict sensor performance, a step-function optical response is typically assumed. This model is then used to predict overall sensor performance and to optimize signal processing algorithms. However, pixels rarely exhibit this ideal behavior. Two deviations in ideal response are described: a pixel center region degradation and an exponentially decaying region on the outside of the pixel corresponding to carrier diffusion. The corresponding MTFs are calculated and the effect on matched filters and sensor performance is modeled.
