| 摘 要： | 理论上推导了通过偏振CCD光学系统的部分偏振光在透射过程和反射过程中偏振特性的变化，定量计算了特定参数下的入射部分偏振光束经过特定单透镜透射后偏振度的分布，给出了偏振度变化的数量级，计算表明一定偏振度的入射部分偏振光束经过透射后，由于偏振度的变化和光线的入射高度以及视场角都有关系，光束偏振度在出射截面上将产生一定的分布。

| Abstract: | The polarization change during transmission course was analyzed when the partially polarized light beam from an object passed CCD's optical system. A kind of specific case was calculated, and change ranges of polarization are given. Calculations show that polarization degree of partial polarized light beam presents certain distribution on the cross section of transmitted output beam from interface. Changes of polarization degree have not only relation to angle of incidence, but also location of point light source. |
