标题： Numeric simulations build a bridge from a two-slit experiment to the basics of X-ray diffraction and coherent optics

摘要： 基于惠更斯-菲涅尔方法的数值模拟有助于理解相干光在衍射和干涉实验中的行为。 它们提供了一个机会，可以数值地观察和欣赏一些重要的现象，而无需处理其解析描述的复杂性。 在基础教学实验室中，它们有助于构建一个概念矩阵，许多光学演示实验都能很好地融入其中，并有利于学生的学习。 显示英文摘要

摘要： Numeric simulations based on the Huygens-Fresnel method allow one to develop intuition about the behavior of coherent light in diffraction and interference experiments. They give an opportunity to numerically observe and appreciate a number important phenomena, while avoiding the need to deal with the intricacies of their analytic descriptions. In an introductory teaching lab, they help to build a matrix of ideas, into which many optical demonstration experiments fall nicely and to the benefit of a student.
