A schematic representation of the 6D WAXD tensor tomography scanning setup. (a) The detector coordinates and the 3D fibre orientation are described in the laboratory coordinate system. The sample is placed in the incident path (along the xL axis) of the focused X-ray probe. The data acquisition only requires a regular scanning tomography protocol including a raster scan in the yL–zL plane and sample rotation along the yL axis. (b1) A 2D WAXD pattern is acquired at each scanning point, which is further used to retrieve (b2) the (110) reciprocal sphere [QS(110)] corresponding to the illuminated volume in the X-ray path. As a result, (b3) a 2D QS(110) array corresponding to the scanning projection (φ) is obtained for the subsequent voxel reconstruction. (c1)–(c4) Schematics indicate that the simulated sample exhibits similar lattice structure and fibre-symmetry features as mantis shrimp cuticles.
