微角锥棱镜阵列回归反射器衍射特性

Diffractive Properties of the Micro-prism Retro-reflectors

本文利用角锥棱镜阵列单元有效反射面积的反演投影法 ,计算了两种角锥棱镜阵列回归反射器的衍射特性。具体计算了不同观测角、不同单元尺度下角锥棱镜阵列的光强反射率 ,指出两种角锥棱镜阵列回归反射器在衍射特性上的差异 。

Using the method to calculate the unit available retro-reflective area,we have computed the retro-reflectivity at both different unit edge length and different observation angles.We also point out the difference of the diffractive properties between the two types of retro-reflectors.
