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 …

In 1999, researchers extended X-ray crystallography to allow the imaging of noncrystalline
specimens by measuring the X-ray diffraction pattern of a noncrystalline specimen and then …

The deformation, flicker, and drift of a light field owing to complex media such as a turbulent
atmosphere have limited its practical applications. Thus, research on invariants in randomly …

Coherent x-ray diffraction microscopy is a method of imaging nonperiodic isolated objects at
resolutions limited, in principle, by only the wavelength and largest scattering angles …

We present the first experimental demonstration of lensless diffractive imaging using
coherent soft<? format?> x rays generated by a tabletop soft-x-ray source. A 29 nm high …

For centuries, lens-based microscopy, such as optical, phase-contrast, fluorescence,
confocal, and electron microscopy, has played an important role in the evolution of modern …

This work demonstrates nanoscale magnetic imaging using bright circularly polarized high-
harmonic radiation. We utilize the magneto-optical contrast of worm-like magnetic domains …

There are many different strategies that allow the solving of the well-known phase problem
corresponding to the loss of phase information during a physical measurement. In …

Two modified Gerchberg–Saxton (GS) iterative phase retrieval algorithms are proposed. The
first we refer to as the spatial phase perturbation GS algorithm (SPP GSA). The second is a …

X-ray free-electron lasers (X-FELs) produce X-ray pulses with extremely brilliant peak
intensity and ultrashort pulse duration. It has been proposed that radiation damage can be …
