(a) Scheme of the white-beam experimental set-up for imaging ferroelectric domains in periodically poled crystals. (b) Experimental and (c) simulated images of a lithium niobate crystal (period = 14.8 µm, 006 reflection, E = 12.4 keV) for different sample-to-detector distances. The phase modulation used for the simulations is a periodic rectangular profile with a phase shift of 140°.
