(a) Mirror reflection law of symmetric Bragg reflection. The virtual source S′ is exactly the mirror image of the real point source S with respect to the crystal surface (z = 0). (b) Relationship between the lateral divergence angle φ and the azimuthal angle Φ on the crystal surface (z = 0). The inset indicates the cross section of the divergent beam viewed along the direction opposite to the beam direction.
