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

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 crystallography provides the vast majority of macromolecular structures, but the
success of the method relies on growing crystals of sufficient size. In conventional …

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 ptychographical iterative engine (or PIE) is a recently developed phase retrieval
algorithm that employs a series of diffraction patterns recorded as a known illumination …

X-ray lasers offer new capabilities in understanding the structure of biological systems,
complex materials and matter under extreme conditions,,,. Very short and extremely bright …

Abstract Theory predicts,,, that, with an ultrashort and extremely bright coherent X-ray pulse,
a single diffraction pattern may be recorded from a large macromolecule, a virus or a cell …

Analytical tools that have spatial resolution at the nanometre scale are indispensable for the
life and physical sciences. It is desirable that these tools also permit elemental and chemical …

Holography provides access to the optical phase. The emerging compressive phase
retrieval approach can achieve in-line holographic imaging beyond the information-theoretic …

Very high resolution X-ray imaging has been the subject of considerable research over the
past few decades. However, the spatial resolution of these methods is limited by the …
