Paper Abstract

The article proves the problem of determining the mechanical vibration amplitudes of complicated movements by optical homodyne interferometry to be incorrect. The possibility of its approximate solution by the least-squares method is presented. The above method usage for the restoration of mechanical system vibration spectrum has been verified.
