Abstract

Cryogenically cooled infrared detectors are known to have better temperature resolution and shorter integration time as compared to the uncooled “competitors”. These advantages allow for longer detection distances, better spatial resolution and the ability to detect fast moving objects. However, high ownership cost of the mechanical cryogenic refrigerator, along with tough export regulations, prevent the widespread deployment of cryogenically cooled infrared imagers in the commercial marketplace. CRYOTECH LTD reports on the development of cost-effective, low size, weight, and power cryogenic solutions for commercial high operational temperature infrared imagers. The authors present the outcomes of the feasibility study, predictions of theoretical performance along with size and weight assessments.
