光的干涉现象为光的波动性提供了有力的证据,光的干涉也是光学教学中的重要内容,是波动光学的基础之一。在教学中,对光的干涉进行实验教学,作为对理论教学的有效补充,但是想在实验中很好观察干涉现象却有一定的难度,实验中单缝和双缝之间不平行或不对齐、光没有聚焦到单缝、观察镜调整不到位等,都很难清楚地观察到干涉条纹从而影响教学效果。为解决这一难题,采用计算机模拟干涉现象是一种很好的方法,就采用计算、绘图功能强大的MATLAB模拟干涉现象。
The phenomenon of light interference provides strong evidence for the fluctuation of light. Light interference is also an important part in optical teaching and is one of the foundations of wave optics. In teaching, experimental teaching on light interference is an effective complement to theoretical teaching. However, it is difficult to observe the interference phenomenon well in experiments. In the experiment, there is no parallel or misalignment between single-slit and double-slit , The light does not focus on a single slit, observation mirror adjustment is not in place, it is difficult to clearly observe the interference fringes and thus affect the teaching effect. To solve this problem, using computer simulation of interference phenomenon is a good way to use computing, drawing powerful MATLAB simulation of interference phenomenon.
