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…
Video-rate gigapixel ptychography via space-time neural field representations
Ruihai Wang, Qianhao Zhao, Zhixuan Hong +14
Achieving gigapixel space-bandwidth products (SBP) at video rates represents a fundamental challenge in imaging science. Here we demonstrate video-rate ptychography that overcomes…
Multiscale aperture synthesis imager
Ruihai Wang, Qianhao Zhao, Tianbo Wang +7
Synthetic aperture imaging has enabled breakthrough observations from radar to astronomy. However, optical implementation remains challenging due to stringent wavefield synchroniza…
