Paper Abstract

A method of amplitude determination of mechanical vibrations from the spectrum of autodyne signal of semiconductor laser is described. The relation between the vibration amplitude of an object and the frequency of spectral component with the maximal amplitude in the spectrum of the autodyne signal is obtained. The least-squares method is used to obtain the approximation coefficient. Measurements of vibration amplitude of piezoelectric plate were carried out with the help of a semiconductor laser autodyne system.
