摘要
理论上分析了金属表面的反射偏振特性,计算了不同偏振方位角的线偏振光45°入射镀铝反射镜后反射椭圆光的偏振参量,并进行了实验验证.模拟及实验结果表明:金属复折射率和入射角度一定的情况下,圆偏振度与入射线偏振光的振动方向有关,理论计算和实验测得的最大圆偏振度分别为;24.75%、12%,材料的复折射率不同是引起偏差的主要原因。
The polarization properties of metal reflector were analyzed. When linear polarization light was incident on aluminium mirror, tilted 45° about its vertical axis, the elliptical polarization parameters were simulated and measured. Simulated and experimental results indicate： When metal complex index of refraction and incident angle are constant, circular polarization is related to linear polarization angle of the incident light. The maximum circular polarization of 24.75%, 12% is obtained by simulation and experiment. The aberration is from the difference of compex index of refraction.
