Interactive Tutorial about Diffraction
Current version: 2.1
This is a pictorial guide to crystal structures and their Fourier transforms useful for teaching diffraction physics. The examples of structures and their Fourier transform, presented in this tutorial, have grown from courses on diffraction physics taught at the Department of Crystallography in München and now at the Department of Crystallography in Würzburg. The interactive examples were first developed for a class on scattering taught at the Physics department at Michigan State University. You have to have javascript enabled in order to run the interactive examples.

All examples have been calculated by use of DISCUS, a program written to simulate any type of structure and to calculate the corresponding Fourier transform in any section of reciprocal space. For details on the concept of this tutorial and how to integrate it into lectures, see
