反射偏光片穆勒矩阵研究

Study on mueller matrix of reflecting polarizer

采用穆勒偏光显微镜实验测量出了吸收偏光片和反射偏光片的穆勒矩阵,基于吸收偏光片的琼斯矩阵和穆勒矩阵理论,推导出了反射偏光片的琼斯矩阵和穆勒矩阵的表达式,并给出了线偏振光的偏振方向与反射偏光片透光轴之间的夹角为0°、45°和90°等特例情况下的计算结果,与实际情况相符。在此基础上,进一步计算了反射偏光片与吸收偏光片组合时的情况,提出非对称透视膜和电控镜原理与应用展望。

The Mueller matrix of absorbing polarizer and reflective polarizer are measured by Mueller polarization microscope,based on the Jones matrix and Mueller matrix theory of absorbing polarizer,the Jones matrix and Mueller matrix expression of reflective polarizer are deduced.The results are given when the polarization angle between linearly polarized light and the transparent axis of reflective polarizer are 0°,45°and 90°,they agree with the actual situation.On this basis,the results of the combination of the reflective polarizer and the absorbing polarizer are further calculated,the principle and application prospect of asymmetric perspective film and electronic controlled mirror are presented.
