摘要
提出了一种新颖的,在已知四分之一波片快轴方向的情况下,利用两个偏振片和一个三棱镜来提高波片相位延迟角测量精度的简便方法,给出了对该方法的理论分析与不确定度公式,并给出了应用实例 此方法的主要优点是可以提高测量精度,并且操作简单。
A novel method used for the enhancement of the accuracy of the measurement of the retardance of a quarter-wave plate employing two polaroids and a prism is reported under the condition of knowing the direction of the fast axis of the plate. The theoretical analysis of the principle and the uncertainty formula are given. An application example is also demonstrated. The measured result of the example is verified with an experiment. The main advantages of this method include the accuracy enhancement, simple measuring setup and easy operation.
