| 摘 要： | 分析了线偏振光垂直入射到角锥棱镜经三个直角面依次反射后出射光线偏振态的变化。利用衍射理论，计算了出射光两正交偏振分量各自的远场衍射分布，模拟出了相应的光场衍射分布图，并将计算结果与不考虑偏振态情况下的远场衍射图进行了比较分析，证明两者间存在明显差别。所得结果为不同使用要求下角锥棱镜的理论设计提供了依据。

| Abstract: | The polarization variation of a reflector light after a bundle of linear polarization light is incident on the ideal cube corner retroreflector is analyzed. Diffraction distribution about the orthogonal polarization quantities of a reflector light is calculated with Fresnel diffraction theory and the correlative diffraction diagram is drawn. Meanwhile, the comparision with the diffraction diagram without considering the polarization effect proves that they are different obviously. At the same time, the result provides the grounds for the theoretical design of cube corner reflector with different usage requirement. |
