a Ground truth (top) and reconstructed (bottom) cross-sections of the electron density \({{{\mathcal{A}}}}({{{\bf{x}}}})\) of the synthetic strained crystal with no internal dislocations. The array size represents the original bounding box chosen for reconstruction, i.e., 46 pixels along each lab frame axis. The spatial resolution was estimated by fitting an error function to the reconstructed electron density along the dashed line (see Fig. 3c). b Orthogonal cross sections of ground truth lattice distortion components u1(x), u2(x) and u3(x) The length scale is the same as in a. c Corresponding sections of the reconstructed lattice distortion. The scales shown for u in this and subsequent Figures are in units of fractional lattice constant [ − 0.05α0, 0.05α0]. For comparison, this scale translates to a scale of [−0.1, 0.1] radians when considering the GTu scalar field projection corresponding to the [002] Bragg peak.
