High-resolution X-ray diffraction and imaging
This issue of Journal of Applied Crystallography includes some highlights of the 11th Biennial Conference on High-Resolution X-ray Diffraction and Imaging (XTOP), held in St Petersburg in 2012.
متن کاملHigh-resolution X-ray imaging for lab-based materials research
The extension of limits of X-ray imaging techniques – in terms of spatial and temporal resolution as well as of material contrast – in the energy range from 5 to 70 keV has long exclusively taken place at third generation synchrotron beamlines. Yet, by using the latest generation of lab-sources together with novel X-ray detectors, results from microas well as sub-micrometer imaging are obtained...
متن کاملDevelopment of an X-Ray Interferometer for High-Resolution Phase-Contrast X-Ray Imaging
An X-ray interferometer for high-resolution phase-contrast X-ray imaging was developed by thinning the central part of the analyzer crystal of a triple Laue-case (LLL) X-ray interferometer. The interferometer was tested at beamline 47XU at the SPring-8, and the improvement of the resolution of interference patterns was successfully observed for a plastic sphere of 1 mm diameter.

The latest virtual special issue of Journal of Applied Crystallography includes some highlights of the 12th Conference on High-Resolution X-ray Diffraction and Imaging (XTOP), which took place in Villard-de-Lans and Grenoble in September 2014.
متن کاملHigh-resolution X-ray lensless imaging by differential holographic encoding.
We demonstrate in the soft x-ray regime a novel technique for high-resolution lensless imaging based on differential holographic encoding. We have achieved superior resolution over x-ray Fourier transform holography while maintaining the signal-to-noise ratio and algorithmic simplicity. We obtain a resolution of 16 nm by synthesizing images in the Fourier domain from a single diffraction patter...
