| 中文摘要: |
| 为了分析施密特棱镜对自然光和部分偏振光的传输特性,使用Pauli旋转矩阵把施密特棱镜的Jones矩阵转换成Mueller矩阵。将一束部分偏振光经过施密特棱镜后分成两路偏振度相同的部分偏振光,再把两路部分偏振光各自分解为自然光与椭圆偏振光,发现两路椭圆偏振光的椭率角相同,方位角不同,由此可知两路部分偏振光是不相同的。理论和实验分析均表明,在部分偏振光入射时的偏振度和方位角的关系一定时,出射后两路部分偏振光中的椭圆偏振光的椭率角相等,方位角不等。 |

| In order to analyze unpolarized light and partially polarized transmission characteristics of the Schmidt prism, Pauli rotation matrix is used to convert the Jones matrix of the Schmidt prism to the Mueller matrix. When a bunch of partially polarized light goes through Schmidt prism, it is divided into two paths, and both of them are partially polarized light, with the same degree of polarization. The two bunches of partially polarized lights are decomposed into unpolarized light and elliptically polarized light. Then we discovered that the ellipticity angle is equal but the azimuth of the elliptically polarized light in the two paths is different. Thus, the two partially polarized lights are not the same. The theoretical and experimental analysis show that the incident partially light's degree of polarization and azimuth are determined after the exit of two partially polarized light. The elliptically polarized light's ellipticity angle is equal, but the azimuth is different. |
