摘要

波前编码(WFC)是一种利用广义非球面光学和数字信号处理来大大增加聚焦深度和/或降低成像系统成本的技术。通常采用三次相元来获得对散焦和一些像差不敏感的图像。在这项工作中，我们将展示如何优化三叶草相板的设计，以优化其对大量散焦的性能。

Optimizing the design of trefoil phase plates for wavefront coding

Wavefront Coding (WFC) is a technique which makes use of generalized aspheric optics and digital signal processing to greatly increase the depth of focus and/or reduce the cost of imaging systems. Usually, cubic phase elements are employed to obtain images that are insensitive to defocus and some aberrations. In this work we will show how to optimize the design of a trefoil phase plate in order to optimize its performance for large amounts of defocus.
