Dose-efficient Automatic Differentiation for Ptychographic Reconstruction
Longlong Wu, Shinjae Yoo, Yong S. Chu +2
Ptychography, as a powerful lensless imaging method, has become a popular member of the coherent diffractive imaging family over decades of development. The ability to utilize low-…

Imaging extended single crystal lattice distortion fields with multi-peak Bragg ptychography
Saugat Kandel, Siddharth Maddali, Marc Allain +4
We describe a phase-retrieval-based imaging method to directly spatially resolve the vector lattice distortions in an extended crystalline sample by explicit coupling of independen…
