In the last two decades, after the first light from the new Free Electron Lasers, either in the
UV (FLASH [1] and FERMI@ Elettra [2]) or X-ray (LCLS [3] and SACLA [4]), more and more …

We introduce a coded-mask-based multi-contrast imaging method for high-resolution phase-
contrast and dark-field imaging. The method uses a binary phase mask designed to provide …

ABSTRACT A fascinating way of generating speckle patterns is by interfering the weak fields
scattered by a disordered sample with the intense trans-illuminating beam. The resulting …

The advent of next-generation synchrotron radiation sources and X-ray free-electron lasers
calls for high-quality Bragg-diffraction crystal optics to preserve the X-ray beam coherence …

X-ray near-field speckle-based phase-sensing approaches provide efficient means of
characterizing optical elements. Presented here is a theoretical review of several of these …

When a macroscopic-sized noncrystalline sample is illuminated using coherent x-ray
radiation, a bifurcation of photon energy flow may occur. The coarse-grained complex …

We introduce a new X-ray speckle-vector tracking method for phase imaging, which is based
on the wavelet transform. Theoretical and experimental results show that this method, which …

High-quality bi-concave 2D focusing diamond X-ray lenses of apex-radius R= 100 µm
produced via laser-ablation and improved via mechanical polishing are presented here …

A neural-network machine learning model is developed to control a bimorph adaptive mirror
to achieve and preserve aberration-free coherent X-ray wavefronts at synchrotron radiation …
