Abstract

Recent years have seen increasing interest in PtSi infrared imaging systems. The performance and capabilities of a 5122 element PtSi imager have been assessed, and various figures of merit describing system linearity, spatial uniformity, and noise equivalent temperature are presented and contrasted with similar performance figures obtained from a 3-5 micrometers CMT system. The superior spatial uniformity and poorer thermal sensitivity of the PtSi imager is contrasted with the CMT system which generally exhibits poorer spatial uniformity but significantly higher thermal resolution. Trade-off studies between fixed-pattern noise and thermal resolution are discussed in terms of overall system performance for both imagers.
