Abstract :
The model of cylindrical blackbody cavity sensor is established based on finite element thermal analysis method. By comparing the emissivity of cylindrical blackbody cavity and its combinations, including sphere cylindrical, conical-cylindrical, and truncated cone cylindrical blackbody cavity, the optimum design of the blackbody cavity is obtained. The results show that the emissivity of truncated cone-cylindrical blackbody cavity is higher, especially when it has small aperture, long cavity, and far distance between cavity and detector.
