Abstract
A phase grating for a phase contrast X-ray imaging device has a transverse surface which is to be aligned substantially transversely with respect to a radiation incidence direction and which is spanned by an x-axis and a y-axis perpendicular thereto. The phase grating is formed from a multiplicity of grating webs composed of a basic material, which are arranged alternately with optically denser interspaces. The grating webs subdivide the transverse surface into grating strips which are in each case elongated in the y-direction and which are lined up parallel alongside one another in the x-direction. The phase grating has in each grating strip along a z-axis, which is perpendicular to the transverse plane, a homogeneous total thickness of the basic material which always differs between adjacent grating strips. At least one grating web extends within the transverse surface over a plurality of grating strips.
