Abstract

This paper presents a compilation of information on the history and features of thermo-electric coolers, infrared detectors and their combination into detector/cooler packages. It shows their potential for utilization as the thermal infrared sensors in those measurement devices related to the problems of energy conservation in building envelopes. General sensor considerations are reviewed in light of present and future applications and features of a typical commercial instrument using thermoelectrically cooled detectors are presented. The history, evolution and features of the cooler detector package, which is the heart of the system is presented. The presentation highlights the desirable attributes of these often overlooked thermoelectrically cooled detectors. Features such as low cost, high reliability, low power, lightweight and long life make them more appreciated and attractive to future commercial instrumentation designs.
