Figure 2
(a) Bragg-diffraction image and (b) phase image, recorded at d = 20 cm, of holes (H) in an icosahedral Al–Pd–Mn quasicrystal. The letters R are aimed to help identify the same region on both images. The diffraction image shows that the presence of a hole is associated with a distortion (D1 in the main figure and D in the magnification) of the quasicrystal in its neighbourhood. g is the projection of the diffraction vector on the image plane.
