Performance and optimization of X-ray grating interferometry

Sensitivity of X-ray grating interferometry.

It is known that the sensitivity of X-ray phase-contrast grating interferometry with regard to electron density variations present in the sample is related to the minimum detectable refraction angle. In this article a numerical framework is developed that allows for a realistic and quantitative determination of the sensitivity. The framework is validated by comparisons with experimental results...

Holotomography versus X-ray grating interferometry: A comparative study

X-ray grating interferometry with a liquid-metal-jet source

X-ray Interferometry

For the astronomer, x-ray interferometry is the theory and practice of building dilute aperture telescopes for studying celestial x-ray sources. The short wavelengths and high surface brightness of x-ray sources will make the eventual scientific payoff very high, with direct imaging of the event horizons of black holes as the centerpiece. In this article we review the history of x-ray interfero...

Hard X-ray phase-contrast tomography of non-homogeneous specimens: grating interferometry versus propagation-based imaging.

X-ray phase-contrast imaging is an effective approach to drastically increase the contrast and sensitivity of microtomographic techniques. Numerous approaches to depict the real part of the complex-valued refractive index of a specimen are nowadays available. A comparative study using experimental data from grating-based interferometry and propagation-based phase contrast combined with single-d...
