摘　　要：本文用多层介质膜系的特征矩阵 ,对反射全息图的理论衍射效率进行计算 ,讨论了以 DCG为记录介质的反射全息光栅的偏振特性 ,主要采用计算机模拟的方法分析了反射全息图对 p-偏振光和 s-偏振光两种再现情况下的光谱响应 ,并给出了实验验证的结果。我们看到 :在一定条件下 ,反射全息图的衍射效率很大程度上取决于入射光的偏振状态。最后 。The diffraction efficiency of reflection hologram is theoretically calculated by using the character matrix of multilayer medium films. The polarization characters of reflection holographic grating recorded in dichromated gelatin are discussed, while the diffraction properties are analyzed respectively for p-polarized light and s-polarized light by computer simulation. Experimental results are presented. We see that the diffraction efficiency of reflection hologram can be highly dependent on the polarization of incident light. In conclusion, the way to choose right polarization component in practical application is brought forward.
