摘要
系统研究了照明光的波前曲率对PIE成像分辨力的影响，证明采用弯曲波前的照明光可以显著提升PIE对随机噪声和量化误差的抗干扰能力，从而能够使重建图像的分辨力提高3倍以上，为实际实验中照明光的选择提供了指导。
Abstract
Curved illumination is used to improve the performance of ptychographical iterative engine (PIE). Influence of illumination with different curvatures on PIE is studied. Results show that curved illumination can make the algorithm more robust to random noise and quantization error, and enhance the resolution of PIE more than three times. Thus a good reference to the choice of illumination in the PIE experiment is given.
