Shear displacement gradient in X-ray Bragg coherent diffractive imaging [PDF]

Journal of Synchrotron Radiation, 2022
Bragg coherent X-ray diffractive imaging is a cutting-edge method for recovering three-dimensional crystal structure with nanoscale resolution. Phase retrieval provides an atomic displacement parallel to the Bragg peak reciprocal lattice vector.

In situ coherent diffractive imaging [PDF]

Nature Communications, 2018
Coherent diffractive imaging (CDI) allows for high resolution imaging without lenses. Here, Lo et al. develop in situ CDI with real-time imaging and a corresponding low-dose requirement, with expected applications in the physical and life sciences.

Pushing the resolution limit of coherent diffractive imaging [PDF]

Light: Science & Applications
Coherent diffractive imaging (CDI), with its lensless geometry and theoretically perfect transfer function, is considered as one of the most promising paradigms to achieve the Abbe resolution limit.

Reduction of artifacts associated with missing data in coherent diffractive imaging [PDF]

Journal of Synchrotron Radiation
Coherent diffractive imaging experiments often collect incomplete datasets containing regions that lack any measurements. These regions can arise because of beamstops, gaps between detectors, or, in tomography experiments, a missing wedge of data due to ...

Coherent diffractive imaging of microtubules using an X-ray laser [PDF]

Nature Communications, 2019
XFEL radiation is providing new opportunities for probing biological systems. Here the authors perform nanoscale x-ray imaging of microtubules with helical symmetry, by using imaging sorting and reconstruction techniques.

Experimental 3D coherent diffractive imaging from photon-sparse random projections [PDF]

IUCrJ, 2019
The routine atomic resolution structure determination of single particles is expected to have profound implications for probing structure–function relationships in systems ranging from energy-storage materials to biological molecules.

Mapping the 3D position of battery cathode particles in Bragg coherent diffractive imaging [PDF]

Journal of Synchrotron Radiation, 2023
In Bragg coherent diffractive imaging, the precise location of the measured crystals in the interior of the sample is usually missing. Obtaining this information would help the study of the spatially dependent behavior of particles in the bulk of ...

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 ...

Considerations for three-dimensional image reconstruction from experimental data in coherent diffractive imaging [PDF]

IUCrJ, 2018
Diffraction before destruction using X-ray free-electron lasers (XFELs) has the potential to determine radiation-damage-free structures without the need for crystallization. This article presents the three-dimensional reconstruction of the Melbournevirus
