Serial coherent diffraction imaging of dynamic samples based on inter-frame constraint
Pengju Sheng, Fucai Zhang
We proposed a novel approach to coherent imaging of dynamic samples. The inter-frame similarity of the sample's local structures is found to be a powerful constraint in phasing a s…

Robust Ptychographic Reconstruction with an Out-of-Focus Electron Probe
Shoucong Ning, Wenhui Xu, Pengju Sheng +5
As a burgeoning technique, out-of-focus electron ptychography offers the potential for rapidly imaging atomic-scale large fields of view (FoV) using a single diffraction dataset. H…

A high-performance reconstruction method for partially coherent ptychography
Wenhui Xu, Shoucong Ning, Pengju Sheng +4
Ptychography is now integrated as a tool in mainstream microscopy allowing quantitative and high-resolution imaging capabilities over a wide field of view. However, its ultimate pe…
