窄带部分偏振光的统计
Statistics of narrow-band partially polarized light
摘要：
利用电场矢量的二维周期平均概率密度函数（PA-PDF），给出了窄带部分偏振光场的一个完整的单点统计描述。该统计量可以使用相干（外差）检测来测量。与传统的Stokes矢量相比，PA-PDF携带了更多关于部分偏振光的信息。对于一个简单的高斯部分偏振场，PA-PDF依赖于13个实参数，而Stokes矢量或相干张量的参数只有4个
英文摘要：
A complete single-point statistical description of a narrow-band partially polarized optical field is developed in terms of the 2-D Period-Averaged Probability Density Function (PA-PDF) of the electrical field vector. This statistic can be measured using the coherent (heterodyne) detection. PA-PDF carries more information about the partially-polarized light than the traditional Stokes vector. For a simple Gaussian partially polarized field the PA-PDF depends on 13 real parameters in contrast to the four parameters of the Stokes vector or coherence tensor
