Super-large scale infrared detector test Dewar

The invention discloses a super-large-scale infrared detector test Dewar which comprises a vacuum system, a refrigeration system, a temperature measurement and control system and a black body system. The vacuum system is used for providing a vacuum environment required by testing; the refrigerating system is used for providing a mounting platform, a low-temperature cold source and a low-temperature cold background environment for the detector; the temperature measurement and control system is used for monitoring the temperature of each component and controlling the temperature of the refrigerating system; and the blackbody system is used for providing a signal source for the photoelectric performance test of the detector. According to the invention, the problem of testing the photoelectric performance of the super-large-scale spliced infrared detector is solved. 本发明公开了一种超大规模红外探测器测试杜瓦，包括：真空系统、制冷系统、测控温系统和黑体系统；真空系统，用于提供测试所需的真空环境；制冷系统，用于为探测器提供安装平台、低温冷源和低温冷背景环境；测控温系统，用于监测各部件温度、控制制冷系统温度；黑体系统，用于为探测器的光电性能测试提供信号源。本发明解
