Example of experimental data: a rocking curve around the nominal value for the Q = [[{\overline 1}, {\overline 1}, {\overline 1}]] reflection (ϕ = 0) of the aluminium single crystal studied. As the sample is rotated away from ϕ = 0, the mean intensity of the acquired images (blue line) decreases. Insets of raw images are added at different points of the rocking curve, illustrating the strong-beam condition (crystal lattice in diffraction) and the weak-beam condition (dislocation distortion fields in diffraction), until the sample is completely rotated out of the diffraction condition. Most of the images used in this work were acquired at 8 × 10−4°, highlighted in red. The images in the insets have a FOV of 260 × 200 µm.
