摘要
利用Matlab编程实现对菲涅尔波带片狭缝方程的可视化,为照相法制作振幅型波带片提供图样。结果表明:该方法生成图样时间短、效率高。最后分析了影响图样设计精度的因素,并得出结论:波带片焦距越短或者波带片半径越大,精度越低;计算点数越少,精度越低。
Using Maflab programming to realize visualization for slit equation of fresnel zone plate, it provides samples for making amplitude-zone plate with photographic process. The results indicate that this method is fast and efficient. Factors of influence on design-accuracy of samples are analyzed, and it is concluded that the focal distance of zone plate is shorter or the radius of zone plate is longger, the accuracy is lower; the computing points arefewer, the accuracy is lower.
