The possibility of reconstructing the shape of an interference signal on the basis of the autodyne detection signal of a semiconductor laser is demonstrated in cases of harmonic and nonharmonic vibrations of the object of study. The shape of the interference signal coincides with the shape of the signal of an interference system decoupled from the radiation source. It is shown that the form of nonharmonic vibrations can be reconstructed from the values of the autodyne signal function at four varying distances from the external vibrating reflector. Numerical simulation of the procedure of reconstruction of the shape of the interference signal was performed. The main limitations of the method under consideration are discussed.
