Journal ArticleDOI
Differential x-ray phase contrast imaging using a shearing interferometer
TL;DR: In this paper, an x-ray interferometer was developed that uses two transmission phase gratings to analyze wave front distortions in the hard X-ray range, which was used for differential phase contrast imaging of low absorbingbing test objects.
Journal ArticleDOI
X-ray wavefront analysis and optics characterization with a grating interferometer
TL;DR: In this paper, an interferometric method was proposed to measure the shape of a hard-x-ray wavefront, which consists of a phase grating as a beam splitter and an absorption mask for the detector.
Journal ArticleDOI
Diamond planar refractive lenses for third- and fourth-generation X-ray sources.
TL;DR: The fabrication and testing of planar refractive hard X-ray lenses made from bulk CVD diamond substrates is reported, which should be able to withstand the extreme flux densities expected at the planned fourth-generation X-rays sources.
Proceedings ArticleDOI
Hard x-ray phase imaging and tomography with a grating interferometer

TL;DR: In this paper, a two-grating interferometer for hard X-ray imaging and tomography is proposed, which can be used for phase imaging and image tomography.
Journal ArticleDOI
Wavelength tunable diffractive transmission lens for hard x rays
TL;DR: In this article, the authors report on the fabrication and testing of linear transmission Fresnel zone plates for hard x-rays, which are generated by electron beam lithography and chemical wet etching of 〈110〉 oriented silicon substrates.
