Classification of polycrystalline diffraction patterns. We categorize them on the basis of center detection challenges: (a), (b) and (d) with beamstops, (b) broken rings, (c) reconstruction artifacts, (c) and (d) strong noise/background, and (e) flat background. Samples: (a) and (e) Au nano-islands, (b) Ag crystals, (c) Fe3O4 nanoclusters, and (d) ZnO–CuO nanoparticles.
