Abstract
The paper deals with the problems to be solved for the creation of a digital speckle interferometer that makes it possible to study vibration of mechanical elements excited simultaneously at several frequencies. The method of registering specklograms has been developed on the basis of methods of holography and speckle-interferometery. Separate spectral components of surface oscillations in case of broadband object stimulation are shown. The method developed is based on time modulation of laser beams in the interferometer.
