Figure 5
Split-crystal interferometer. Displacements of the splitter (S), mirrors (M1 and M2), and analyser (A) as seen by a neutron entering the splitter at time [t = 0] and traversing the interferometer along the first (blue line) and second (red line) arms. Since the moving crystals drag the neutron and the displacements related to the accelerated diffracting planes — see (1a) — have been omitted, the perceived displacements halt. The dashed lines are the motions of the first (green) and second (orange) block, which are made to coincide at [t = 0]. The arrows indicate the jumps of the second block perceived (because of the crystals' drag) when the neutron leaves the first.
