论文摘要
本文介绍了一种从旋转偏振器后测得的强度的各种极化椭圆的明确重建和可视化的方法。光束的极化状态由实验室设置定义的实验室坐标系中的电场振幅矢量的变化表示。通过旋转偏振器后测得的光束的强度给出了与偏振器的波电场成分的估计值，该偏振器在一个时间段内平均平均轴线。在偏光仪坐标系中估计正交场分量和极角的估计公式已得出。正交极化的组件和极角都是从强度测量中推导的椭圆参数的函数。最后，将最终的电场和极角映射到实验室坐标系，并与从Stokes载体获得的极化椭圆的表示。
This paper describes a method for the explicit reconstruction and visualization of various polarization ellipses from the intensities measured after a rotating polarizer. The state of polarization of a light beam is represented by the variation of the electric field amplitude vector with polar angle in the laboratory coordinate system defined by the experimental set-up. The intensity of the light beam measured after passing through a rotating polarizer gives the estimate of the wave electric field component parallel to the polarizer pass axis averaged over a time period. The formulae for the estimation of orthogonal field component and polar angle, in the polarizer coordinate system have been derived. Both the orthogonally polarized components and the polar angle are functions of ellipse parameters that have been deduced from the intensity measurements. Finally, the resultant electric field and the polar angle are mapped to the laboratory coordinate system and compared with the representation of the polarization ellipse obtained from the Stokes vectors.
