摘要

介绍了测量材料表面双向反射分布函数和发射率的原理和方法，搭建了532 nm和1 064 nm波长双向反射分布函数和表面发射率测量平台，对经金刚砂（320目）研磨后金属靶板表面的反射率和发射率及中等温升情况下的变化特性进行了实验测量。测量结果表明，粗糙金属靶板表面近似为朗伯辐射体，反射率低于0.25。在常温至320℃范围内，靶板表面反射分布、反射率和发射率的变化幅度较小。

Abstract

The principle and method of surfaced bi-directional reflective distribution function (BRDF) and irradiation were introduced. The measuring platform of surfaced BRDF on 532 nm/1 064 nm and irradiation was built to study the temperature dependence of the reflectance and irradiation of metallic target grided by emery(320 mesh). The results show that the ground metallic target approximates lambert radiator

and the reflectivity is lower than 0.25. The surfaced reflective distribution

reflectivity and irradiation are almost consistence below 320℃.
