In 1993, Inframetrics introduced the InfraCAMTM to the commercial marketplace. It established the standard for hand-held, lightweight, low power, portable infrared sensors that is still unmatched in the industry. Under contract to the U.S. Army's Night Vision and Electronic Sensors Directorate, Inframetrics has integrated numerous detector technologies into a common system platform. This paper reports on a unique system for evaluating detector technologies using common electronics. The technologies covered are as follows: Platinum Silicide (PtSi) in the short wave infrared band (1.0 - 2.5 micrometers ), PtSi, Indium Antimonide and Mercury Cadmium Telluride in the mid wave infrared band (3.0 - 5.4 micrometers ), and HgCdTe and Quantum Well Infrared Photodetector in the long wave infrared band (8 - 12 micrometers ). The comparison criteria is primarily 3D noise (temporal and spatial) and Minimum Resolvable Temperature Difference. Additionally, non-uniformity correction circuitry, developed specifically to accommodate more sensitive, less stable detectors, is characterized.
