Fast cool down I.R. detectors
Abstract
The design problems posed by fast cooldown requirements in IR detectors' sensor elements are discussed with a view to the relative advantages of Joule-Thomson coolers and a two-stage thermoelectric cooler. Typical applications for these devices are next-generation heat-seeking and laser-guided missiles, which must become operational after only a few seconds. The unit prices of these detectors must be low by comparison with those used in thermal imaging systems.
