Optimal design of 3-D superresolution pupil filter
-
摘要: 利用matlab优化工具箱，采用非线性规划，对三区振幅型（透过率为101）和三区位相型（相位角为0）光瞳滤波器进行三维超分辨优化设计，建立了优化模型，经计算机多次迭代运算，改变斯特尔比s值，给出了优化结果。结果显示：所设计的滤波器较好地实现了横向和轴向三维超分辨，且轴向超分辨能力优于横向；相同斯特尔比下，位相型三维超分辨能力优于振幅型，并且这两种滤波器结构简单，容易实现。Abstract: Three-zone amplitude-type superresolution pupil filters (1-0-1) and three-zone phase-type superresolution pupil filters (-0-) are designed with Matlab optimization toolbox and non-linear programming. The optimal model is established and some examples of optimization are given. The optimization results show the both filters have preferable 3-D superresolution characteristics, the axial resolution is better than transverse resolution, and the phase-type resolution is better than amplitude-type resolution at the same Strehl ratio. The structures of the both filters are simple and easy to be implemented.
