中文摘要：

本文基于四波段双向反射分布函数测试平台,对微粗糙硬铝表面的光谱双向反射分布函数进行了实验测量,考察了微粗糙尺寸参数、入射角度和入射辐射波长对表面辐射特性的影响。测量结果显示了明显的镜反射特征,粗糙的表面结构还引起了后向反射增强现象,长波入射和大角度入射增强后向反射效应。

英文摘要：

The spectral bidirectional reflectance distribution functions（BRDF） of duralumin with micro-roughness are measured by means of four bands BRDF test platform.More,the effects of roughness,incident angle and incident wavelength on surface radiation properties are also studied.Experimental results reveal a specular reflection characteristic.Furthermore,rough surface,incident laser with long-wavelength or big incident angle improve the backward scattering enhancement phenomenon.
