Computer-generated phase-only diffractive optical elements in a cascaded setup are designed by one deterministic and one stochastic algorithm for multiplane image formation. It is hypothesized that increasing the number of elements as wavefront modulators in the longitudinal dimension would enlarge the available solution space, thus enabling enhanced image reconstruction. Numerical results show that increasing the number of holograms improves quality at the output. Design principles, computational methods, and specific conditions are discussed.
在级联设置中，通过一种确定性算法和一种随机算法设计用于多平面图像形成的计算机生成的纯相位衍射光学元件。据推测，增加纵向维度上作为波前调制器的元件数量将扩大可用的解空间，从而实现增强的图像重建。数值结果表明，增加全息图的数量可提高输出质量。文中讨论了设计原理、计算方法和具体条件。
