Weak-beam contrast for studying dislocations with line beam illumination in monochromatic and pink radiation cases. In this case the pink beam was attenuated by a 50 µm Cu foil. (a) Rocking curves obtained by summing intensities in each detector pixel over all images in the DFXM rocking scan. The intensity of the rocking curves was normalized to 1 to facilitate direct comparison. The blue curve was acquired with the monochromatic beam and the orange curve with the pink beam. Weak-beam contrast images: (b) Monochromatic beam at a rocking angle corresponding to 20% of the maximum intensity [blue dashed line in (a)]. (c) Pink beam at a rocking angle corresponding to HWHM [innermost orange dashed line in (a)]. (d) Pink beam at a rocking angle corresponding to 20% of the maximum intensity [outermost orange dashed line in (a)].
