Chapter 2.7 Topography

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; moire topography; and real-time viewing of topograph images. Keywords: double-crystal topography; incident-beam monochromatization; moire topography; reflection topographs; single-crystal topography; synchrotron radiation; topography; white radiation
