(a) Sketch of the experimental geometry with coordinate systems and goniometer angles indicated. The α rotation is around the laboratory y axis and the β rotation around the laboratory x axis. At α = β = 0 the laboratory and sample coordinate systems coincide. (b) Measured sample orientations plotted as (α, β) points. The measured directions are limited to a range of β ≤ 45° by the geometry of the goniometer. The closely spaced points at β = 0 correspond to a normal tomography geometry. (c) A 3D rendering of the reconstructed sample, showing the shape and orientation of the reconstructed symmetry axis. A zoomed-in view is shown in Fig. 6(a). The dashed circle marks the position of the voxel of interest plotted in Fig. 3. |
