When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

Phase recovery (PR) refers to calculating the phase of the light field from its intensity
measurements. As exemplified from quantitative phase imaging and coherent diffraction …

X-ray ptychographic microscopy combines the advantages of raster scanning X-ray
microscopy with the more recently developed techniques of coherent diffraction imaging. It is …

Linear accelerator-based free-electron lasers (FELs) are the leading source of fully coherent
X-rays with ultra-high peak powers and ultra-short pulse lengths. Current X-ray FEL facilities …

We study the problem of recovering the phase from magnitude measurements; specifically,
we wish to reconstruct a complex-valued signal about which we have phaseless samples of …

A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

X-ray crystallography has been central to the development of many fields of science over the
past century. It has now matured to a point that as long as good-quality crystals are …

The problem of phase retrieval, ie, the recovery of a function given the magnitude of its
Fourier transform, arises in various fields of science and engineering, including electron …

X-ray computer tomography (CT) is fast becoming an accepted tool within the materials
science community for the acquisition of 3D images. Here the authors review the current …
