摘　　要：设计了一种基于二维光栅分光的线偏光Stokes参量测量系统.将二维正交光栅的4束(±1,±1)级衍射光作为探测光束入射到检偏器阵列的4个单元上,每个单元是具有不同方位角的检偏器,然后由CCD探测器同时探测.利用二维正交光栅、检偏器阵列和面阵CCD探测器实现了同步移相功能.利用CCD探测的4束光强度可以得到线偏光的Stokes参量.实验结果表明,本方案简单易行,测量结果不受光源强度变化的影响.A measurement system for Stokes parameters of linear polarized light based on orthogonal grating was presented. Four diffractive beams of （±1,±1） orders were incident on one of the analyzer in the ana- lyzer array respectively. The analyzer array is composed of four analyzers with different polarization directions. The intensities of light through the analyzer array were detected by a CCD simultaneously. The simultaneous phase shifting is realized by an orthogonal grating, analyzer array and CCD detector. Linear Stokes parameters of incident light were obtained by calculation of detected light intensities. The experimental results indicated that the designed method was feasible and simple. In addition, the measured resuh is free of the intensity fluctuation of incident light.
