摘要发射率分布测量是评价大口径辐射源辐射均匀性的重要基础,但目前针对相关参数的研究较为匮乏。基于全半球激光积分反射方案,设计搭建了基于积分球反射法的红外辐射源发射率分布特征测量系统;开展了测量系统的性能研究,评价了激光光源子系统的稳定性,并在3W的激光器功率下开展了面辐射源发射率分布特征测量实验。结果表明:建立的测量系统的稳定性良好,以标准金板表面为研究对象,多次测量结果的重复性为0.30%;开展了碳基面辐射源发射率分布实验测量,获得面辐射源发射率的分布云图,发射率的均匀性为98.1%。

Abstract：The measurement of emissivity distribution characteristics is an important basis for evaluating the radiation uniformity of large-aperture radiation sources, but the related research is relatively scarce at present. Therefore, a measurement system for the emissivity distribution characteristics of the infrared radiation source is designed and built based on complete hemispherical laser integrated reflection scheme. The performance of the measurement system is studied, the stability of the laser light source subsystem is evaluated, and the experiment of measuring the emissivity distribution characteristics of surface radiation source is carried out at 3 W laser power. The results show that the measurement system has good stability. Taking the surface of standard gold plate as the research object, the repeatability of multiple measurement results is 0.30%; The experimental measurement of emissivity distribution of carbon based surface radiation source is carried out, and the distribution cloud map of emissivity of surface radiation source is obtained, the uniformity of emissivity is 98.1%.
