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…

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…
