Iterative Algorithms for Ptychographic Phase Retrieval

C. Yang, J. Qian, A. Schirotzek, F. Maia, S. Marchesini

摘要:

重叠关联成像承诺衍射极限分辨率,而不需要高分辨率透镜。为了实现高分辨率,必须解决许多部分重叠帧的相位问题。在这里,我们回顾了一些现有的方法,从数值分析的角度来解决重叠关联相位恢复问题,并提出了基于数值优化的替代方法。

英文摘要:

Ptychography promises diffraction limited resolution without the need for high resolution lenses. To achieve high resolution one has to solve the phase problem for many partially overlapping frames. Here we review some of the existing methods for solving ptychographic phase retrieval problem from a numerical analysis point of view, and propose alternative methods based on numerical optimization.
