Abstract

An improved modular FLIR system is provided that fits in the same space elopes that were provided for the Army's GEN I FLIR's. The resolution is more than doubled by using a narrow two dimensional array of Hg-Cd-Te detectors with pn junctions as a time-delay-integration line sensor, improved optics and analog-digital conversion with image enhancement.
