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.

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.

Fresnel coherent diffractive imaging tomography of whole cells in capillaries
New Journal of Physics, 2014 X-ray tomography can be used to study the structure of whole cells in close to their native state. Ptychographic Fresnel coherent diffractive imaging (FCDI) holds particular promise for high-resolution tomographic imaging with quantitative phase ...
