偏振光干涉计量中的椭圆偏振化误差分析

Error Analysis of Elliptic Polarization in Polarized Interferometry

主要分析两束相互垂直的线偏振光经过金属反射镜反射后引起的椭圆偏振化的不对称性，并研究由此产生的非线性误差的变化规律，这对提高偏振光外差干涉仪的测量精度是极为重要的。

This paper analyzes the non-symmetry of elliptic polarization of two linear polarized beams, which are perpendicular to each other, caused by their reflecting from a metal mirror. Also, it studies the non-linear error created by polarization and how the errors change. The study is very important for improving the measuring accuracy of polarized heterodyne interferometer.
