摘要

摘要: 为了精确地测量旋光效应中偏振光的旋光角度及其分布，提出了基于偏振分束成像的旋光角度场测量新方法。分析和推理论证了旋光角度场测量理论基础，设计构建了光电检测验证系统，即根据偏振光分束原理，借助于高清晰度CCD采集图像，由计算机对图像进行中值滤波和基于奇异值的匹配处理，再采用差除和信号处理以消除光源波动的影响，得到检测结果。实验结果表明，与传统的测量方法相比，该方法不受光源波动的影响，能精确、快速地检测旋光角度二维分布场，并具有很好的线性，数据的均方差仅为传统测量方法的40%。

Abstract: In order to measure the rotation angle and the distribution of polarized light in optical rotation effect accurately, a new method based on polarization beam imaging is proposed. The theory of the rotation angle of field measurement is reviewed and the system of photoelectric detection is designed. With a polarized beam splitter, the light is split into S light and P light which are acquired by a high resolution CCD. The image is filtered by a median filter, the matching processing based on singular value is implemented, and signal processing is used to eliminate the source fluctuations. The results show that it can detect the two-dimensional distribution of rotation angle from the light source fluctuation rapidly and accurately, and the standard deviation is only 40% of the traditional measurement methods.
