Two spherical waves and multiple spherical waves interference , and yang ' s interference experiments are simulated by using different methods . two spherical waves interference is focused on the on - plane or out - plane of the spot light source plane and the observing plane . then , we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern
用光波波前叠加的方法实现了对两列球面波干涉、多光束干涉等实验的仿真；用传播矩阵描述衍射光波波前传播的方法对杨氏双缝和双孔干涉实验进行了仿真，并具体详细地分析了单缝衍射对双缝干涉的影响；另外还分析了光场的时间相干性对干涉条纹反衬度的影响。
