Abstract
Determination method of the mechanical vibration amplitudes by the spectrum of the autodyne signal of the semiconductor laser for the sphericity of the light wave front is described. The relation between the focusing of the laser beam and form of the autodyne signal was obtained. Measurements of the vibration amplitude of the piezoelectric plate were carried out with the help of the semiconductor laser autodyne system.
