Residual neural-field ptychography for dose-efficient electron, X-ray, and optical nanoscopy
Qianhao Zhao, Zhixuan Hong, Ruihai Wang +7
Ptychography spans from sub-angstrom to meter scales yet suffers from convergence instability and excessive data redundancy. Here we introduce self-correcting residual neural field…
