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 sources are developing rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …

Microscopy has greatly advanced our understanding of biology. Although significant
progress has recently been made in optical microscopy to break the diffraction-limit barrier …

Coherent diffraction imaging (CDI) is high-resolution lensless microscopy that has been
applied to image a wide range of specimens using synchrotron radiation, X-ray free-electron …

We overcome two of the most daunting challenges in single-particle diffractive imaging:
collecting many high-quality diffraction patterns on a small amount of sample and separating …

We demonstrate the advantages of imaging with ptychography scans that follow a Fermat
spiral trajectory. This scan pattern provides a more uniform coverage and a higher overlap …

We have developed an algorithm that combines the concept of optimization with the
conventional hybrid input-output (HIO) algorithm for phase retrieval of oversampled …

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 …

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 …
