Abstract

A large format prototype infrared camera based on the MOSAD (Multiplexed OverSample A/D converter) concept was developed and demonstrated. Each pixel readout buffer is composed of a two integrator one bit modulator that converts the accumulating photon induced charge to a digital value. This camera is designed around a 640 X 480 pixel focal plane array with an A/D converter at each pixel. The focal plane is a CMOS design readout hybridized to a MWIR (3 - 5 micron) N on P Mercury Cadmium Telluride detector array with pixels placed on 27 micron centers. Amain developed and tested the readout, camera and electronics. Rockwell Science Center provided the detectors which they hybridized to the Amain readout.
