Abstract
The paper presents a contactless measurement of mechanical structure vibrations based on the Doppler effect. The range of the measured velocities and amplitudes of the mechanical vibrations and the errors of the measurement method are analysed. The range of applicability of the method as well as measurement results of the vibrations of a loudspeaker and a loudspeaker cabinet are also presented.
