粗糙表面镜向散射光强统计

粗糙表面散射可分为镜向散射和非镜向散射, 镜向散射光强的分析不仅具有理论上的简洁性, 而且能够给出粗糙表面散射的一些重要特性。论文根据相干散射和傅里叶光学理论, 对粗糙表面的镜向散射光场进行了理论分析和推导, 结果表明: 镜向散射光场的主要特征由粗糙表面高度分布的傅里叶变换和入射光场的傅里叶变换共同决定。对于均匀平行光照射高斯表面情形, 镜向散射光强是有效粗糙度的高斯函数, 镜向散射光强在焦平面的分布为 sinc平方函数。

Abstract

Statistics on reflective light intensity of rough surfaces is not only based on simple theory, but also able to give the most important features of rough surface scattering. The theoretic analysis and deduction of reflective light field of rough surface is performed, and the results suggest that the key features of reflective light field of rough surface is determined by the Fourier transform of rough surface highness distribution and the incident light field. In case of Gauss surface illuminated by uniform parallel light, the reflective intensity is a Gauss function of the effective roughness, and its distribution on the focal plane is a sinc square function.
