Laboratory Evaluations of Competing Uncooled FPA Technologies

Abstract

Comparison of performance requirements are presented for a Raytheon (Amber) Sentinal Uncooled Micro-Bolometer Focal Plane Array (UMFPA) camera and a Raytheon (formerly Texas Instruments Defense Systems and Electronics Group) Technology Reinvestment Project (TRP) Ferroelectric Uncooled Focal Plane Array (UFFPA) camera. The two cameras were tested for numerous performance-related issues involving time, temperature, FPA region and image translation related dependencies. The performance parameters of interest were 1) nonuniformity versus environmental temperature 2) Changes in non-uniformity with time since power up and as a function of time since non-uniformity collection update, 3) Noise Equivalent Temperature Difference (NETD), 4) V-curves, 5) Minimum Resolvable Temperature Difference (MRTD), 6) response linearity, 7) power consumption and readiness time as a function of system soak temperature, and 8) image smear distortion characteristics.
