Dynamic diffraction artefacts in Bragg coherent diffractive imaging. [PDF]

open access: yesJ Appl Crystallogr, 2018
This article reports a theoretical study on the reconstruction artefacts in Bragg coherent diffractive imaging caused by dynamical diffraction effects. It is shown that, unlike the absorption and refraction effects that can be corrected after reconstruction, dynamical diffraction effects have profound impacts on both the amplitude and the phase of the ...

The fluence-resolution relationship in holographic and coherent diffractive imaging. [PDF]

open access: yesJ Appl Crystallogr, 2017
This work presents a numerical study of the fluence–resolution behaviour for two coherent lensless X-ray imaging techniques. To this end the fluence–resolution relationship of inline near-field holography and far-field coherent diffractive imaging are ...

Nonlinear ptychographic coherent diffractive imaging [PDF]

open access: yesOptics Express, 2016
Ptychographic Coherent Diffractive Imaging (PCDI) is a significant advance in imaging allowing the measurement of the full electric field at a sample without use of any imaging optics.

Potential of attosecond coherent diffractive imaging [PDF]

open access: yesPhysical Review Letters, 2019
Attosecond science has been transforming our understanding of electron dynamics in atoms, molecules and solids. However, to date almost all of the attoscience experiments have been based on spectroscopic measurements because attosecond pulses have ...

Noise-robust coherent diffractive imaging with a single diffraction pattern [PDF]

open access: yesOptics Express, 2012
The resolution of single-shot coherent diffractive imaging at X-ray free-electron laser facilities is limited by the low signal-to-noise level of diffraction data at high scattering angles.

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

open access: yesIUCrJ, 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

The linac coherent light source single particle imaging road map [PDF]

open access: yesStructural Dynamics, 2015
Intense femtosecond x-ray pulses from free-electron laser sources allow the imaging of individual particles in a single shot. Early experiments at the Linac Coherent Light Source (LCLS) have led to rapid progress in the field and, so ...

Dynamic Coherent Diffractive Imaging with Modulus Enforced Probe and Low Spatial Frequency Constraints [PDF]

open access: yesSensors
Dynamic behavior is prevalent in biological and condensed matter systems at the nano- and mesoscopic scales. Typically, we capture images as “snapshots” to demonstrate the evolution of a system, and coherent X-ray diffraction imaging (CDI), as a lensless

Temporal Coherence Effects on Coherent Diffractive Imaging of a Binary Sample by a High Harmonic Source

open access: yesEPJ Web of Conferences, 2013
Coherent Diffractive Imaging (CDI) is performed with single and multiple harmonics from an ultrafast HHG source. The effect of HHG source bandwidth on the effectiveness of the reconstruction algorithms is compared.
