Polarization is a kind of transmit modality of light, and we can understand detect information from the other one dimensionality by polarization information. Polarization imaging contains rich target parameters including spectrum, radiant intensity, polarization state, space geometry, etc in which can improve the target detection and recognition ability. Based on the bidirectional reflectance distribution function model, the paper establishes Infrared radiation transmission equation of object surface, and we deduce the mathematical model with respect to a lot of factors of the degree of polarization. Aim at the infection of circumstance factors, a lot of experiment of the Infrared polarization and the Infrared hyper-spectral polarization imaging about different material and standard blackbody were developed. The result show that the infrared degree of polarization of blackbody is not relate to wave length, and the method of infrared polarization quantitative analysis is put forward that is based on the infrared polarization characteristics of standard blackbody.
