(a) Measured transmission coefficient of the direct beam in the orientation looking straight down the enamel layer. (b) A 3D rendering of the sample geometry and a scattering cone with an opening angle of 2θ = 20°. The model of the sample is colored according to the reconstructed fractional anisotropy, which highlights the difference between the highly aligned enamel (red) and the more isotropic dentine (blue/green). Panels (c) and (d) show the azimuthal variation of the scattered intensity at the points marked by crosses in (a) for the 002 and 004 Bragg peaks, respectively, where the distance from the center is proportional to the square root of the measured intensity. Missing data points are due to overlap of the Bragg peaks with gaps in the X-ray detector.
