Diffraction topography is the formation of images of crystals using Bragg‐diffracted rays. Topics covered in this chapter include: the principles of diffraction topography; single‐crystal techniques, including reflection and transmission topographs; double‐crystal topography; the use of synchrotron radiation; moiré topography; and real‐time viewing of topograph images.
