Finite Element Analysis of Thermal Stress of 2048×2048 HgCdTe Infrared Focal Plane Dewar Cold Head
Xiong XIONG, Ming-deng HU, Jian-le WU, yu DUAN, Yong-qiang ZHOU, Yu DU, and Jian-hong MAO
The original structure and the added balance layer structure of the 2048×2048 (15 m) infrared focal plane dewar cold head are analyzed by finite element method. Adding a balance layer with a lower expansion coefficient under the ceramic substrate can relieve the deformation and thermal stress of the detector chip

A Design Method of Cold Shield for Infrared Detectors
Ya TIAN, Zhi-kai FU, and Guan WANG
Aiming at the problems of large number of clapboards and difficult assembly process in the traditional design scheme of infrared detector cold shield, a simplified design method of infrared detector cold shield is proposed in this paper. This method reduces the number of cold shield partitions, the thermal mass of cold
