Compact InSb Staring Imager

摘要

This paper describes a low cost, high performance, compact imager. It utilizes 64 * 64 pixels InSb staring FPA sensor that is a miniature dewar cooler assembly, cooled by a J-T cooler. The imager achieves NETD of less than 0.1K at 300K background with f/1.4 optics at 50Hz frame rate. It can be used in imaging guidance or other military and civil systems.
