A Kind of Two-Stage Refrigeration Gas Supply System for Infrared Detector Design

Two-stage refrigeration gas supply system adopts the method of "one cylinder,two cavities,independent charge"to realize that the first stage cavity powerfully refrigerates the detector beforehand,the second stage cavity persistently refrigerates the detector for long time.This artide detailedly introduces the component parts,working principle,structure design,characteristics and application prospect of two-stage refrigeration gas supply system for infrared detector.
