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 …

We demonstrate simultaneous phase and amplitude extraction from a single defocused
image of a homogeneous object. Subject to the assumptions explicitly stated in the …

Multilayer Laue lenses are volume diffraction elements for the efficient focusing of X-rays.
With a new manufacturing technique that we introduced, it is possible to fabricate lenses of …

X-ray interferometry for imaging applications is discussed with a review of X-ray
interferometric imaging activities reported to date. Phase measurement and phase …

We propose an alternative method for solving the Transport of Intensity equation (TIE) from a
stack of through–focus intensity images taken by a microscope or lensless imager. Our …

We demonstrate 3D phase and absorption recovery from partially coherent intensity images
captured with a programmable LED array source. Images are captured through-focus with …

Optical imaging beyond the diffraction limit, ie, optical superresolution, has been studied
extensively in various contexts. This paper presents an overview of some mathematical …

Over the past 15 years, ptychography applications and methods have advanced
significantly. Ptychography is a computational microscopy technique for acquiring images …

Phase contrast x-ray imaging of small animal lungs reveals a speckled intensity pattern not
seen in other tissues, making the lungs highly visible in comparison to other organs …
