一种快速同时测量波片相位延迟量和快轴方位角的方法
|
摘要
基于Mueller矩阵和斯托克斯矢量的测量原理及方法,实现了对波片相位延迟量和快轴方位角的快速同时测量。激光通过偏振片和标准1/4波片后产生标准的右旋圆偏振光入射待测波片,用斯托克斯测量仪记录通过样品后激光的斯托克斯矢量,同时得到待测波片的相位延迟量和快轴方位角;分析了标准1/4波片的参数误差及系统稳定性对测量结果的影响。利用该实验系统测量得到的波片相位延迟量和快轴方位角的平均标准差分别为±0.05°和±0.03°,同时,得到了云母波片及石英波片的参数与温度的实验关系。所提方法具有测量过程简单、精确度高及可以对未知各向异性材料相位延迟量及其等效快轴方位角进行实时测量等特点。
Based on the measurement principle and the method of Mueller matrix and Stokes vector, the phase retardation and fast axis azimuth of wave plate are measured rapidly and simultaneously. After the laser passing through the polarizer and the standard 1/4 wave plate, the standard right rotation circular polarized light is produced and then passes through the wave plate sample. The Stokes vector of the laser after passing through the sample is recorded by the Stokes polarimeter,and the phase retardation and fast axis azimuth are obtained simultaneously. The influences of standard 1/4 wave plate parameter error and system stability on measurement results are analyzed. By using this experimental system, the average standard deviations of the phase retardation and fast axis azimuth of wave plate are ± 0. 05° and ± 0. 03°, respectively.The experimental relationship between the parameters of mica wave plate and quartz wave plate and temperature is also obtained. The proposed method has the characteristics of simple measurement process, high precision and real-time measurement of phase retardation and equivalent fast axis azimuth of unknown anisotropic material.
