论文摘要
我们建议对Wigner分布反卷积（WDD）进行修改，以支持实时处理Ptychography。实时处理允许在获取衍射模式时逐渐重建和显示样品传输功能。为此，我们重新制定WDD并采用降低维度的技术，以降低记忆消耗并提高处理速度。我们在数值上表明，这种方法维持了样品传输函数的重建质量，并在采集过程中降低了计算复杂性。尽管我们仅介绍用于扫描传输电子显微镜（STEM）数据集的重建，但通常，我们在本文中提出的实时处理算法可以应用于不同应用领域的实时Ptychographic Reconstruction。
We propose a modification of Wigner Distribution Deconvolution (WDD) to support live processing ptychography. Live processing allows to reconstruct and display the specimen transfer function gradually while diffraction patterns are acquired. For this purpose we reformulate WDD and apply a dimensionality reduction technique that reduces memory consumption and increases processing speed. We show numerically that this approach maintains the reconstruction quality of specimen transfer functions as well as reduces computational complexity during acquisition processes. Although we only present the reconstruction for Scanning Transmission Electron Microscopy (STEM) datasets, in general, the live processing algorithm we present in this paper can be applied to real-time ptychographic reconstruction for different fields of application.
