Abstract

Grating interferometer comprising inclined phase grating structures, method for increasing the definition of phase contrast images of interferometers or in applications which are based on the Talbot effect, using inclined phase grating structures, phase gratings wherein the grating structures are positioned at angles on the substrate of the phase grating, method for producing grating structures which are positioned at angles on the substrate of the phase grating, and corresponding uses.
