Phase-contrast x-ray imaging (PCI) is an innovative method that is sensitive to the refraction
of the x-rays in matter. PCI is particularly adapted to visualize weakly absorbing details like …

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 …

Over the past decade, computed tomography (CT) theory, techniques and applications have
undergone a rapid development. Since CT is so practical and useful, undoubtedly CT …

We present a simple x-ray phase imaging method that utilizes the sample-induced distortion
of a high contrast random intensity pattern to quantitatively retrieve the two-dimensional …

We report on the observation and application of near-field speckles with a laboratory x-ray
source. The detection of speckles is possible thanks to the enhanced brilliance properties of …

In the past few years, X-ray phase-contrast and dark-field imaging have evolved to be
invaluable tools for non-destructive sample visualisation, delivering information inaccessible …

We demonstrate an extension of the x-ray grating interferometer three modal imaging
method to a generalized stepping scheme using a phase object with small, random features …

We describe an x-ray differential phase-contrast imaging method based on two-dimensional
transmission gratings that are directly resolved by an x-ray camera. X-ray refraction and …

Phase-sensitive X-ray imaging methods can provide substantially increased contrast over
conventional absorption-based imaging, and therefore new and otherwise inaccessible …

We present a method for x-ray phase-contrast imaging and metrology applications based on
the sample-induced modulation and subsequent computational demodulation of a random …
