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…

Deep-ultraviolet ptychographic pocket-scope (DART): mesoscale lensless molecular imaging with label-free spectroscopic contrast
Ruihai Wang, Qianhao Zhao, Julia Quinn +11
The mesoscale characterization of biological specimens has traditionally required compromises between resolution, field-of-view, depth-of-field, and molecular specificity, with mos…
