摘 要: | 摘 要:本文提出波前编码成像系统的一种优化设计思想,可以利用常用光学设计软件进行系统的优化设计。采用此设计思想设计出一采用波前编码技术的三片式系统,其焦深范围比传统系统扩展10倍以上。最后探讨了波前编码系统设计时“离焦不敏感性”和“图像可恢复性”之间的平衡问题。

A novel optimization method for Wavefront Coding |
| |
Abstract: | Abstract:A novel optimization method for Wavefront Coding systems was designed, the method can be used to design Wavefront Coding systems just through commercial optical software, Code Ⅴ、Zemax etc. A triplet system was designed, and the Wavefront Coding technology added to the systems, which extend the depth of focus much than 10 times. At the end, a normal problem in the designning of Wavefront Coding systems, the trade-off between 'the insensitivity to defocus' and 'the restorablity' was discussed. |

Keywords: | depth of focus wavefront coding(WFC) phase mask optimization |
