Paper Abstract

A response model that describes an optimal imager with a photodiode-direct injection readout focal plane is developed and a time-domain computer simulation based on this model is executed for different background radiance levels. For small signals, the model explains in detail why small photodiode capacitance, and high background photoflux levels are necessary to maintain good optical resolution. However, unlike the small-signal model, the large-signal model is valid throughout the range of parameters and gives the response for large signal-to- noise ratio and low background cases.
