Data obtained by computation for X-ray imaging of grating with magnification factor equal 2 using oriented Gaussian beams
Dane BadawczeThe propagation of X-ray waves through an optical system consisting of grating and X-ray refractive lenses is considered. In this approach, the propagating wave is represented as a superposition of the oriented Gaussian beams. The direction of wave propagation in each Gaussian beam is consistent with the local propagation direction of the X-ray wavefront.
