中文摘要:
研究了一种基于强度传输方程(TIE)和角谱迭代传播算法的混合迭代算法。通过仿真和实验,对比了TIE算法与混合迭代算法在不同离焦距离下的相位恢复效果。结果表明,与TIE算法相比,混合迭代算法提升了大离焦距离下的相位恢复精度,同时提高了相位恢复的空间分辨率。该算法为高精度相位恢复提供了解决方案。

英文摘要:
A hybrid iterative algorithm which combines the transport of intensity equation (TIE)with the iterative angular spectrum propagation algorithm is studied.In the simulations and experiments,the phase retrieval performances by the TIE algorithm and the hybrid iterative algorithm at different defocusing distances are compared. The results indicate that,if compared with those by the TIE algorithm,the accuracy at large defocusing distance and spatial resolution of the phase retrieval by the hybrid iterative algorithm are improved.This algorithm provides a solution to the phase retrieval with high accuracy.
