Oxidation induced strain and defects in magnetite crystals
Nature Communications, 2019 Oxidation of magnetite has broad implications in geochemistry and environmental science, but its reaction mechanisms are not fully understood yet. Here the authors use Bragg coherent diffractive imaging to show oxidative dissolution of magnetite inducing

Coherent diffraction imaging by moving a lens
Optics Express, 2016 A moveable lens is used for determining amplitude and phase on the object plane. The extended fractional Fourier transform is introduced to address the single lens imaging. We put forward a fast algorithm for the transform by convolution. Combined with parallel iterative phase retrieval algorithm, it is applied to reconstruct the complex amplitude of ...

Multi-wavelength phase retrieval for coherent diffractive imaging
, 2020 Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging ...

Direct single-shot phase retrieval from the diffraction pattern of separated objects
Nature Communications, 2016 Short X-ray pulses from free-electron lasers enable coherent diffractive imaging of noncrystalline objects such as single molecules. Here, the authors reconstructing full image information from a single-shot diffraction pattern by using two sufficiently ...
