用偏振片测量反射相移的方法及其理论分析

提出了一种新颖的、用两个线偏振片即可实现的测量反射相移的方法，给出了测量系统的光路图，在理论上阐述了这种方法的工作原理，做出了有关的计算机仿真结果；同时对该方法产生的测量不确定度进行了理论计算，给出其数学表达式，并对其进行了讨论，最后，本文还将这种测量方法用于ZF－7光学玻璃直角三棱镜斜面上内部反射引入的反射相移的研究中，结果表明理论预期值与实测值比较接近，该方法的优点在于所用偏振器件容易得到，测量系统光路简单，容易实现，特别适用于那些买不到特殊偏振器件如巴俾涅补偿片等而又需要测量反射相移的研究单位。

Novel Method for Measuring Reflection-induced Retardance Employing Polarizers and Its Theoretical Analysis

A novel method is used for the measurement of reflection-induced retardance,and a polarizer and an analyzer is proposed,the measuring optical set-up is given,the principle is theoretically analyzed and its computer simulation results are given.The uncertainty of the method is calculated and the mathematical expression of it is given,too.The results of the theoretical analysis and the uncertainty formula are discussed.Finally,this method is used to measure the reflection-induced retardance induced at the oblique surface of a prism made of ZF-7 optical glass.The theoretically expected result is in accordance with the measured one.The advantages of this method include that the polarization optical devices used are easy to obtain and the measurement optical set-up is simple and easy to realize.This method is especially suitable for those who has to measure the reflection-induced retardance but ccan not obtain some special polarization devices such as Babinet Compensator.
