Gaussian-splatting ptychography via explicit and interpretable primitives
Qianhao Zhao, Zhixuan Hong, David Brady +9
Ptychography overcomes the limits of lenses by co-designing optics and computation. Yet prevailing implementations reconstruct on a pixel grid, where weakly-constrained modes drift…
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…
Ptycho-endoscopy on a lensless ultrathin fiber bundle tip
Pengming Song, Ruihai Wang, Lars Loetgering +8
Synthetic aperture radar (SAR) utilizes an aircraft-carried antenna to emit electromagnetic pulses and detect the returning echoes. As the aircraft travels across a designated area…
