| 摘 要： | 探讨了单色线偏振光源的形状、尺寸和取向对检偏棱镜光强透射比的影响．由于检偏棱镜结构误差的存在，使得棱镜空气隙间光的干涉条件发生了改变，引起透射光强分布的变化，入射光束尺寸越大，光强透射比变化就越稳定，圆形光源入射时，光强透射比对空间入射角和入射点的变化比线光源稳定，偏振线光源入射时，光强透射比随其取向的不同敏感性不一样．

| Abstract: | The effects of shape, size and orientation of polarized light source on light transmission ratio of an air-spaced analyzer are studied. Because of the technological error of the prism, the interference conditions in air layer change, and the light transmission changes correspondingly. The bigger the size of cross-section area of incident beam, the steadier light transmission is; for circle source ininjection, light transmission is steadier with the continuous change of spatial incident angle and the change of incident point; the sensitivity of light transmission is different with the difference of line source orientation. |
