摘要
采用部分偏振光分解的方法,求解得到了部分偏振光相干矩阵和斯托克斯矩阵的一般表达式。通过计算不同描述形式下部分偏振光的偏振度,得出了光学教程上定义偏振度公式P=(Imax-Imin)/(Imax+Imin)适用于部分偏振光,且此公式和由“总光强中完全偏振光所占的百分比”计算得到的偏振度是相等的,从而也验证了部分偏振光分解方法的正确性。
We obtained the general expression of the partially polarized in the form of coherent matrix and Stokes vector adopting the method of decomposition.Calculating the degree of polarization of partially polarized in different descriptive form,the formula P=(Imax-Imin)/(Imax+Imin)defined in the optical course is suited to describing the partially polarized,and the degree of polarization is equal to the percentage which the intensity of completely polarized taken up to the full intensity.Moreover,the correctness of the decomposition method in the partially polarized is verified.
