Research on dewar structure of mercury cadmium telluride infrared detector at high operating temperature
With the rapid development of the third generation infrared detector technology,high operating temperature infrared detector has become an important development direction.This paper reports the research progress of the 11 th Institute of CETC.in the miniaturization,low power consumption and high reliability of Dewar structure of high operat-ing temperature tellurium cadmium mercury infrared detector.Through the optimized design of the Dewar structure,combined with the rotary integral cryogenic chiller K562S short,the component volume is 80 mm ×61 mm × 39 mm,and the weight is 212 g.The HOT component of medium wave cadmium tellurium mercury infrared detector with a starting time of 2.5 min and a working temperature of 150 K has been preliminarily completed,which has laid a cer-tain foundation for the engineering application of high working temperature cadmium tellurium mercury infrared detec-tor,and has certain guiding significance for the miniaturization,low power consumption and high reliability research of high working temperature cadmium tellurium mercury infrared detector.
