一束光通过一个透明圆柱体，圆柱后有一个屏幕，程序最终反映屏幕上的 图象随圆柱半径的变化而变化。其中光强分布是采用相干叠加原理，因为其中采 样点数目不足，所以光强分布的结果和真实的有一定差距。增加采样点数目和改 变采样点范围能够改善输出光强的结果逼真程度。(一束光through a transparent cylinder, a cylindrical post-screen process will ultimately reflect the on-screen image with the cylindrical radius change. Light intensity distribution of which is the principle of coherent superposition, because the insufficient number of sampling points, so light intensity distribution of the results and have some real gaps. Increase in the number of sampling points and to change the scope of sampling points can improve the outcome of the output light intensity the degree of realism.)
