    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))
