Phase-mapping of periodically domain-inverted LiNbO<sub>3</sub> with coherent X-rays

A varying refractive index across a wavefront leads to a change in the direction of propagation of the wave. This provides the basis for phase-contrast imaging of transparent or weakly absorbing materials with highly coherent X-ray beams. Lattice distortions can also change the direction of propagat...
