Index.

"The author has maintained a very readable style for the whole ofthis intensely practical and useful book. It should become astandard text for the development of new laboratory systems or forstudents trying to interpret data from 2D area detector systems ofany type. It will also be of use to anyone setting up a 2D systemregardless of geometry, since the underlying principles of thescattering process and the projection of that scattering are solucidly presented." (Crystallography Reviews, March2011)

"Written by one of the pioneers of the field ... .Forresearchers and graduate students in materials science, chemistry,physics, and pharmaceuticals." (Book News, December 2009)
