Bragg projection ptychography on niobium phase domains [PDF]

, 2017
Bragg projection ptychography (BPP) is a coherent x-ray diffraction imaging technique which combines the strengths of scanning microscopy with the phase contrast of x-ray ptychography.

Refinement for single-nanoparticle structure determination from low-quality single-shot coherent diffraction data

IUCrJ, 2020
With the emergence of X-ray free-electron lasers, it is possible to investigate the structure of nanoscale samples by employing coherent diffractive imaging in the X-ray spectral regime.

Nanoscale imaging of shale fragments with coherent X-ray diffraction [PDF]

Journal of Applied Crystallography, 2020
Despite the abundance of shales in the Earth's crust and their industrial and environmental importance, their microscale physical properties are poorly understood, owing to the presence of many structurally related mineral phases and a porous network structure spanning several length scales. Here, the use of coherent X-ray diffraction imaging (CXDI) to

XFEL coherent diffraction imaging for weakly scattering particles using heterodyne interference

AIP Advances, 2020
The spatial resolution of x-ray free-electron laser (XFEL) coherent diffraction imaging is currently limited by the fluence of XFELs. Here, we clarify this issue by systematically studying the diffraction with a SPring-8 angstrom compact free electron ...

Single-pulse characterization of the focal spot size of X-ray free-electron lasers using coherent diffraction imaging

Journal of Synchrotron Radiation, 2023
The characterization of X-ray focal spots is of great significance for the diagnosis and performance optimization of focusing systems. X-ray free-electron lasers (XFELs) are the latest generation of X-ray sources with ultrahigh brilliance, ultrashort ...

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets [PDF]

Structural Dynamics, 2015
Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction.
