Popis:	We present the results of numerical calculations, the experimental data of studying the fluctuation spectra of speckle-field intensity at longitudinal vibration of diffuse objects. A method has been developed for determining the diffuser vibration amplitude by measuring the amplitude ratios of the first two harmonics of the spectrum.
