摘要

通过基于微面元理论的偏振双向反射分布函数模型, 推导分析了物体表面红外辐射偏振传输方程的Stokes表达式, 得出物体表面红外线偏振度与表面反射率(发射率)、波长、探测角度以及波长、目标与背景辐射差异等参数的数学关系；针对环境因素对红外偏振度的影响, 开展了不同材质以及标准黑体的中、长波红外偏振成像及红外高光谱偏振成像实验, 结果表明:黑体表面的红外偏振度与波长不相关, 进而提出以标准黑体红外偏振特性作为溯源基准进行红外偏振定量处理的方法.

Abstract

Based on the bidirectional reflectance distribution function model, the paper establishes infrared radiation transmission equation of object surface. 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 waved length, and the method of infrared polarization quantitative analysis is put forward that is based on the infrared polarization characteristics of standard blackbody.
