COOLED DETECTING DEVICE

摘要

A detection device for infrared radiation has a detection circuit of infrared radiation equipped with at least one photodetector. A readout circuit is electrically connected to the detection circuit, and is configured to process the signal emitted by the detection circuit. A Joule-Thomson cooler cools a cold table thermally and mechanically connected to the detection circuit and the readout circuit. The cold table including an internal cavity supplied with gaseous mixture. A relief port of the gas mixture is arranged at an input in the internal cavity. An output of the compressor feeds the relief port in a gaseous mixture. The input of the compressor receives the relaxed gaseous mixture from an output of the internal cavity.
