Abstract

CEDIP is the first company to produce commercially available LWIR cameras using HgCdTe (MCT) staring arrays. This range of thermal imagers is available in various configurations including split Stirling cooler and integrated micro machine coolers. The design of thermal imagers with this technology requires advanced signal and image processing in order to correct for array non-uniformities, thermal drift and to display the highest quality images. This paper focuses on some of the technical solutions used inside the camera such as the proprietary DSP electronic board which controls in real time the image quality parameters as well as the optical solutions and lens arrangements which provide sharp and clear images. Experimental data and obtained performances are presented and discussed.
