摘　　要：建立基于杨氏双缝干涉的数学模型,给出基于相对光强的干涉条纹可见度的数学模型,借助MATLAB软件对干涉条纹和可见度进行仿真模拟。结果显示:当正确建立和使用数学模型时,条纹级次越高,两个相邻的亮(暗)纹距离就越近。干涉条纹级次越高,其干涉强度分布曲线越不圆滑。不同的干涉条纹级次,对可见度随光强比的变化没有影响。随着干涉条纹级次的增加,干涉条纹的宽度增大,干涉条纹的可见度降低。该研究对于深入理解波动光学理论的引导具有积极意义。The construction of fringe visibility simulation goes as the following:firstly,establishing a mathematical model based on Young’s double-slit interference;secondly,constructing the mathematical model of interference fringe visibility based on relative light intensity;finally,conducting simulation on interference fringes and visibility by MATLAB software.The results go as the following:when the mathematical model is established and used correctly,the higher the stripe order is,the closer the distance between two adjacent bright(dark)stripes is;the higher the order of interference fringes is,the less smooth the interference intensity distribution curve is;different interference fringe orders have no effect on the change of visibility with light intensity ratio;with the increase of the order of interference fringes,the width of interference fringes increases and the visibility of interference fringes decreases.To conclude,this study is of positive significance to deeply understanding the guidance of wave optics theory.
