本文着重介绍应用非么正变换光学系统中的振幅一相位恢复普遍理论，来实现衍射光学元件的设计，给出相关的方程和迭代算法，通过几个实用的衍射光学元件的设计例子来说明新的设计方法的普遍适用性和有效性。 This article focuses on the general theory of amplitude-phase recovery in a non-positive-transforming optical system, in order to realize the design of the diffractive optical element, and gives the related equations and iterative algorithms. The design examples of several practical diffractive optical elements illustrate the new The general applicability and effectiveness of design methods.
