(a) Definition of angles used for the analytic description of scattering-induced dichroism. (b) WAXS of polyimide Kapton using copper Kα radiation shows a dependence on the direction of the polarization to the fiber axis. This difference leads to a tiny dichroism for the transmitted beam. The scale is chosen in such a way that tiny differences become visible. The central spot contains about 108 photons. (c) Radial dependence of the scattering patterns (azimuthal integral) shows a small difference in scattering at large scattering angles. (d) Azimuthal variation of the scattering for both orientations of polarization becomes more clear after radial integration from 2Θ = 8° to 28°. The graphs were smoothed using low-pass filtering.
