Background Denoising for Ptychography via Wigner Distribution Deconvolution
Ptychography is a computational imaging technique that aims to reconstruct the object of
interest from a set of diffraction patterns. Each of these is obtained by a localized illumination …

Convergence properties of gradient methods for blind ptychography
O Melnyk - arXiv preprint arXiv:2306.08750, 2023 - arxiv.org
We consider blind ptychography, an imaging technique which aims to reconstruct an object
of interest from a set of its diffraction patterns, each obtained by a local illumination. As the …

Live Iterative Ptychography with projection-based algorithms
In this work, we demonstrate that the ptychographic phase problem can be solved in a live
fashion during scanning, while data is still being collected. We propose a generally …
