中文说明：本程序可以仿真波片对偏振光的相位调制过程。用户可以通过改变波片的类型，波片长轴与X轴的夹角，起偏器透光与X轴的夹角，检偏器透光轴与X轴的夹角等参数，来观察屏上光强及透过波片后的偏振光的信息。
English Description：
This procedure can simulation of wave plate phase modulation of the polarization process. Users can easily change the type of wave plate, wave length shaft angle with the x axis, and polarizer light angle with the x axis, and polarizer angle between x axis and transmission axis of parameters, such as to observe the screen intensity and polarized light through a wave of information.
