Abstract

High performance thermal imagers, such a serial and parallel scanned FLIRs are now readily available. In these sensors an array of photo-conductive HgCdTe detectors is scanned over the infrared scene, using a combination of opto-mechanical components to generate a two dimensional display. The replacement of mechanically scanning with electronically addressed 'staring arrays' is very attractive since the all electronic approach allows the fabrication of small light-weight imagers. The performance of staring imagers is determined more by FPA charge handling capacity and residual nonuniformity after compensation and less by choice of detector material or spectral bands. Our analysis and measurements indicate that a 244 X 320 FPA based upon platinum silicide detectors is well suited to meet the requirements of small high performance thermal imagers.
