摘　　要：定量计算了轴外点光源发出的部分偏振光束经界面反射后反射光偏振度与空间坐标及点光源坐标间关系，定量计算了特定参数的入射部分偏振光束经界面反射后的偏振度分布，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界面反射后，反射光束偏振度由于界面反射在反射光束截面上将产生一定分布。偏振度的变化不仅与光线入射角有关。The relation between polarization degree of reflected partial plarized light beam from an off axis object point, and space coordinate and point light source coordinate is analyzed. A kind of specific case is calculated, and change ranges of polarization are given. Calculations show that polarization degree of partial polarized light beam present certain distribution on the cross section of reflected output beam from interface. Changes of polarization degree have not only relation to angle of incidence, but also location of point light source.
