Paper Abstract

Various figures of merit that can be used to describe different aspects of infrared sensor performance are described for sensors using photon detectors in a nearly photon background limited mode. Since photon detectors generate charges or currents by absorption of photons, the analyses are based on photon detectivity rather than power detectivity. Consistent use of such an approach could eliminate much confusion in the specification of infrared detectors and sensors and simplification of performance analyses. Performance parameters are presented for both scanning and staring systems and include optical, detector, and front-end signal processing characteristics.
