移相式激光偏振仪的原理及误差分析

Principles and Error Analysis of Phase Shifted Laser Polarimeter

本文介绍了移相式激光偏振仪的原理及误差分析。在塞纳蒙补偿器系统中,通过改变检偏器方位角对输出光强进行移相,然后测量输出光强并作傅立叶分析,就可精确获得被测件的相位延迟量。

The principles and error analysis of a phase shifted laser polarimeter are described in this paper.The phase difference of Senarmont compensator is shifted by rotating the analyzer.The retardation to be measuredcan be determined by Fourier analysis of intensity measurements.
