Paper Abstract

Blackbody is a crucial device for performance test and radiometric calibration of infrared system. This paper put forward a low-temperature surface blackbody with variable temperature. It works under vacuum and low temperature environment, and can realize the variable temperature control within the range from 130K to 450K by the dual control of liquid nitrogen and electric heating. This paper gave a detailed introduction to the system composition and structure of surface blackbody, introduced the design processes of radiator, temperature controller, temperature control system and other important parts, and analyzed the temperature field distribution of blackbody radiator through finite element software. And test method was used to test performance of the surface blackbody. The results show that the blackbody has good temperature uniformity and temperature stability performance, and is able to provide a benchmark for low temperature test of infrared system.
