摘　　要：直接采用光场叠加方法运用数值计算模拟了杨氏双缝实验,研究了光源宽度、双缝缝宽、双缝间距、光源离双缝距离等因素对干涉条纹的影响.模拟的结果表明,光源宽度的增大、光源到双缝的距离的减小均会使得整个视场中干涉条纹的可见度均匀下降;双缝间距的增大会导致条纹可见度的不均匀下降和条纹密集度的增加.Young s double slits experiment was simulated by means of field superposition and numerical calculations.The effects on the interference fringes by the width of source,the width of slits,and the distance from the source to the double slits were discussed.The results showed that the visibility of the fringes decreased when the width of source and the distance between the two slits decreased.
