英文摘要： The polarized spectral emissivity of materials possesses some special properties that it has a wide prospective application field covering remote sensing, radiation thermometry, and so on. Through the deep study of the change rule of polorized emissivity of materials, the project will explore its application in radiation thermometry. The research involves in three aspects: Fistly, with combination of polarized spectral emissivity measurement technique and polarization technology, a fast and adjustable apparatus of polarized spectral emissivity measurement between 0 and 85 degree will be developed. Secondly, by combining theory and experiment, the change rule of polarized spectral emissivity and the relationship between unpolarized and polarized spectral emissivities (p and s polarized) will be studied. The mathematical model of extremum will be built through the analysis on extremum of polarized spectral emissivity and the corresponding angles and temperatures. By studying the effect of temperature, wavelength on the ratio of p and s polarized spectral emissivity, the corresponding mathematical model will be built. Thirdly, several new radiation thermometries will be explored by use of the change rule of polarized spectral emissivity. The project has important signification and practical value for recognition of the nature of spectral emissivity of materials and promoting the development of radiation thermometry.
