This review provides a brief overview and a discussion of dynamical integrated diffractometry and its functional capabilities. It is demonstrated that the combined use of measurements of integrated diffraction parameters on different diffraction conditions allows determining the parameters of several types of microdefects, which are simultaneously present in a single crystal. These parameters are the total integrated intensity of dynamical diffraction, the contribution of its diffuse component, and their dependences on different diffraction conditions. Examples of the use of integrated diffraction parameters for non-destructive express diagnostics of the characteristics of the defects’ structure of single crystals are discussed.
