(a) Ray-tracing of a parallel incident beam in the first two crystal lenses in real space: the symbols with “prime” are for the lower part of the beam; (b) Schematic of the excitation of the dispersion surface projected onto the plane of incidence in reciprocal space for (a); (c) The ray-tracing of the diffracted beam (black) and the optical refracted beam (gray) for the first crystal according to the corresponding wavevectors.
