Abstract
A miniature, nonevacuated, detector refrigerator assembly for use in infrared imaging systems is described. The assembly incorporates a miniature Joule-Thomson laminar refrigerator which serves as the substrate for the detector subassembly, electrical leads, as well as the primary structural element of the assembly. The detector subassembly is positioned on the cold region of the refrigerator, surrounded by two prefabricated vacuum chambers and capped by an optical window or filter as required. As a result, the detector is easily built and is cooled in an efficient manner.
