A thorough grasp of the figures in this chapter is absolutely essential for any understanding of the CBED technique. Experience shows that few electron microscopists unde

We then specialize to the two-beam case, which provides the quickest and most useful guide to CBED intensity distributions. However, the study of non-centrosymmetric crystals requires the three-beam theory, so this is also treated. Both nondegenerate and degen
