Figure 1
Schematic representation of the different diffraction setups with real or virtual source in the Bragg or Laue cases: (a) real source, real focus (red) in the Laue case or virtual focus (blue) in the Bragg case, (b) real source, virtual focus (red) in the Laue case or real focus (blue) in the Bragg case, (c) virtual source, real focus (red) in the Laue case or virtual focus (blue) in the Bragg case, (d) virtual source, virtual focus (red) in the Laue case or real focus (blue) in the Bragg case. #!L₀ = $[\overline{SO}]$ is the source-to-crystal distance and #!L_h = $[\overline{OF}]$ is the crystal-to-focus distance.
