Quantitative 3D imaging of highly distorted micro-crystals using Bragg ptychography
Peng Li, David Yang, Christoph Rau +3
Bragg coherent diffraction imaging (BCDI) fails to reliably retrieve phases in micro-crystals exhibiting strong strain inhomogeneities, which restricts its applicability. Here we s…

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…
