衍射光学元件的解析分析方法

从波动光学传播的菲涅尔衍射出发，探讨一次光学转换形成任意要求的图形的问题。导得两平行传播平面的函数关系，从而在确定像面分布的条件下可以逆求出原始面的振幅与倍相分布。文中给出了几个实例，充分表明这是有实用价值的一种衍射光学元件设计方法。

A New Analytical Method of Diffractive Optical Element

A new type of optical conformal transformation to form a given image pattern was suggested. The functional relationship of the propagstion between two parallel planes, element plane and image plane, was derived from diffraction principle, so that the distribution of the amplitude and phase on the original objective plane may be determinated by the given image--plane distribution. Several examples shown in this Paper indicate that it is a valuable design method of the diffraction optical element.
