The phenomenon of dispersion amplification of defects’ manifestation in the multiple dynamical scattering pattern was discovered by authors and discussed in [1]. This phenomenon is controlled by the diffraction conditions. Amplification comprises several orders of magnitude (in comparison with the kinematical case of diagnostics). The present work is concerned with discussion of the most important consequences of this phenomenon, which provide the appearance of effects of unique sensitivity of the total (Bragg and diffuse) integral intensity of the dynamical diffraction (TIIDD) to the crystal imperfections and the anomalous contribution of its diffuse component as well as sensitivity of appeared strong TIIDD dependences on the diffraction conditions. New opportunities and examples using the TIIDD measurements, contribution of its diffuse component, and their dependences on various conditions of dynamical diffraction for non-destructive express highly sensitive and informative diagnostics of imperfections of the structure of multiparametric systems are discussed.

Key words: integral dynamical diffractometry, multiparametric diagnostics, microdefects.
