Coherent imaging at the diffraction limit [PDF]

Journal of Synchrotron Radiation, 2014
X-ray ptychography, a scanning coherent diffractive imaging technique, holds promise for imaging with dose-limited resolution and sensitivity. If the foreseen increase of coherent flux by orders of magnitude can be matched by additional technological and analytical advances, ptychography may approach imaging speeds familiar from full-field methods ...

Evaporation of an anisotropic nanoplasma [PDF]

EPJ Web of Conferences, 2019
Intense laser induced plasma dynamics in sub-micron scale helium droplets are monitored by femtosecond time-resolved X-ray coherent diffractive imaging. Anisotropic surface softening and strongly anisotropic shrinking of the plasma core are observed.

Generalized deterministic linear model for coherent diffractive imaging

AIP Advances, 2022
A linear model for coherent diffractive imaging (CDI) is proposed herein. In this model, CDI is expressed as a system of linear equations in the frequency domain of an object and illumination.

Globally Optimized Monochromator for Coherent Diffractive Imaging with Tunable EUV Wavelength [PDF]

, 2022
We demonstrate a dual-optic imaging-spectrometer for high harmonic generation sources, ideal for coherent diffractive imaging in a tunable monochromatic mode.

Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses

Nature Communications, 2021
Cavitation bubbles show many nonlinear characteristics of liquid and gas phase. Here the authors demonstrate coherent diffractive imaging of cavitation bubble using infrared pump and XFEL probe and discuss the formation and evolution of the bubbles.

Deterministic Bragg Coherent Diffraction Imaging [PDF]

Scientific Reports, 2017
AbstractA deterministic variant of Bragg Coherent Diffraction Imaging is introduced in its kinematical approximation, for X-ray scattering from an imperfect crystal whose imperfections span no more than half of the volume of the crystal. This approach provides a unique analytical reconstruction of the object’s structure factor and displacement fields ...

Ensemble Diffraction Microscopy: An Imaging Technique That Allows High-Resolution Diffraction Imaging Using Both Totally and Partially Coherent Sources

IEEE Photonics Journal, 2023
Coherent diffraction microscopy (CDM) is a potential approach to image micromaterials at atomic resolution without crystals. Due to the lack of high-angle scattering, the achieved resolution is limited to several nanometers. Small-angle scattering allows
