Abstract在旋转补偿器椭偏仪(RCE)的基础上,提出了一种自校准的波片相位延迟测量方法。该方法将补偿器的相位延迟作为未知参数,根据Mueller矩阵理论建立了4个非线性方程,求解得到待测波片的相位延迟;实现了补偿器相位延迟的自校准,消除了其定标不准确带来的系统误差,尤其适用于多个波长的波片延迟测量。在此基础上建立了一套波片延迟测量系统,并分析和模拟了各种主要的误差源对系统测量精度的影响。结果表明,对于任意延迟的波片,测量系统最大的系统误差和随机误差分别为0.036°和0.040°。此外,使用该方法分别测量了λ/4波片、λ/2波片、127°波片和空气(不放入任何样品)在波长517.3、525.0、532.4nm处的相位延迟以评估测量系统的性能,其中空气的相位延迟代表测量系统的测量精度,与模拟结果基本一致。
