说明: 一束5W 的线偏振光以Φ = 45 度方位角振动,垂直入射到玻璃 - 空气表面,该光束波长0.6μm,玻璃介质折射率1.54 @0.6m,当入射角θ从0-70 度变化时,通过给定条件,分别完成如下要求:
画出该光束反射光的光强曲线(I-θ);
分析该反射光束的偏振态变化,画出偏振方向变化曲线(φ-θ)和偏振光束相位变化曲线
(Φ-θ)。
(注:光束从光密到光疏的界面,在入射角θ 从0-70 度变化中,包括了临界角θc)(Bunch of linearly polarized light 5W to Φ = 45 degrees azimuth vibration, normal incidence to the glass- air surface, the beam wavelength 0.6μm, glass refractive index 1.54 @ 0.6m, when the incident angle θ changes from 0-70 degrees By the given conditions, namely the completion of the following requirements: Draw the reflected light beam intensity curve (I-θ) analysis of changes in the polarization state of the reflected beam, draw the polarization direction of the curve (φ-θ) and polarized beam phase curve (Φ-θ). (Note: the light beam from the optical density of the interface is sparse, the incident angle θ variation from 0-70, including the critical angle θc))

差别阈值法
在第三步的后处理过程中,主要基于人类视觉的一些特性。人类视觉分为低照度下的暗视觉和正常照明下的明视觉以及中间视觉。在暗视觉条件下,人类视觉的对比度分辨率很低。因此,根据退化模型恢复出来的图像虽然对比度很高,细节比较丰富,但由于暗视觉条件下,没有达到人类视觉对比度分辨率的阈值,所以仍然不能被人类视觉感知。因此,需要通过增强图像的亮度,使图像适合人眼观察。人类视觉对比度分辨率阈值称为JND(Just-noticeable
difference),定义为在一幅背景均匀的图像中,人的视觉系统所能感知的、均匀物体与背景之间的最小亮度差异。
