Simultaneous Multi-Bragg Peak Coherent X-ray Diffraction Imaging [PDF]
Crystals, 2021 The simultaneous measurement of two Bragg reflections by Bragg coherent X-ray diffraction is demonstrated on a twinned Au crystal, which was prepared by the solid-state dewetting of a 30 nm thin gold film on a sapphire substrate. The crystal was oriented

Methods of Coherent X-Ray Diffraction Imaging [PDF]
Crystallography Reports, 2021 Abstract Methods of coherent X-ray diffraction imaging of the spatial structure of noncrystalline objects and nanocrystals (nanostructures) are considered. Particular attention is paid to the methods of scanning-based coherent diffraction imaging (ptychography), visualization based on coherent surface scattering with ...

Performance Evaluation of Deep Neural Network Model for Coherent X-ray Imaging
AI, 2022 We present a supervised deep neural network model for phase retrieval of coherent X-ray imaging and evaluate the performance. A supervised deep-learning-based approach requires a large amount of pre-training datasets. In most proposed models, the various
