Schematic illustration of the hard X-ray magnifying set-up. A waveguide delivers a coherent and divergent beam which is transmitted through the sample (at the distance Z1 from the waveguide) and propagates from there a distance Z2 towards the position-sensitive detector. While the wavefronts are almost perfectly spherical at the position of the sample (emitted by a point source coincident with the exit of the waveguide), they are distorted behind the object. |
