Journal ArticleDOI
On the possibilities of x-ray phase contrast microimaging by coherent high-energy synchrotron radiation
TL;DR: In this paper, a straightforward experimental setup for phase contrast imaging is proposed and used to record holographic images from organic samples of 10-100 pm at energy lo-50 keV with the contrast up to 50%-100%.
Journal ArticleDOI
A compound refractive lens for focusing high-energy X-rays
TL;DR: In this article, a simple procedure for fabricating refractive lenses that are effective for focusing of X-rays in the energy range 5-40 keV is described, and the problem associated with absorption is minimized by fabricating the lenses from low-atomic-weight materials.
Journal ArticleDOI
Phase-contrast microtomography with coherent high-energy synchrotron x rays
TL;DR: In this article, the cross-sectional information on low electron density materials can be obtained by probing a sample with a 60 keV coherent synchrotron x-ray beam in an in-line holography setup.
Journal ArticleDOI
Direct measurement of transverse coherence length of hard X rays from interference fringes
TL;DR: A simple interferometric technique for hard x-ray spatial coherence characterization, recording a Fresnel interference pattern produced by a round fiber or a slit, derived analytical formulas that give a direct relation between a visibility of interference fringes and either the source size or the transverse coherence length.
Journal ArticleDOI
Diffraction theory of imaging with X-ray compound refractive lens
TL;DR: In this paper, the parabolic X-ray compound refractive lens (XCRL) with concave surfaces for hard Xray focusing and micro-imaging is analyzed theoretically.
