标题： Ptychography using Blind Multi-Mode PMACE

摘要： 全息成像是一种成像技术，通过用重叠的照明模式扫描物体，能够实现复数透射图像的纳米级重建。 然而，照明函数通常是未知的，这给重建带来了挑战，尤其是在使用部分相干光源时。 在本文中，我们引入了盲多模式投影多智能体一致性平衡（BM-PMACE）用于盲全息成像重建。 我们将PMACE框架扩展到分布式逆问题，以联合估计复数透射图像和多个未知的部分相干探针函数。 重要的是，我们的方法保持局部探针估计，以利用多个探针位置的互补信息。 我们的方法还结合了一种动态策略来整合额外的探针模式。 通过使用合成和测量数据的实验模拟和验证，我们证明BM-PMACE在重建质量和收敛速度方面优于现有方法。 显示英文摘要

摘要： Ptychography is an imaging technique that enables nanometer-scale reconstruction of complex transmittance images by scanning objects with overlapping illumination patterns. However, the illumination function is typically unknown, which presents challenges for reconstruction, especially when using partially coherent light sources. In this paper, we introduce Blind Multi-Mode Projected Multi-Agent Consensus Equilibrium (BM-PMACE) for blind ptychographic reconstruction. We extend the PMACE framework for distributed inverse problems to jointly estimate the complex transmittance image and multiple, unknown, partially coherent probe functions. Importantly, our method maintains local probe estimates to exploit complementary information at multiple probe locations. Our method also incorporates a dynamic strategy for integrating additional probe modes. Through experimental simulations and validations using both synthetic and measured data, we demonstrate that BM-PMACE outperforms existing approaches in reconstruction quality and convergence rate.
