Reconstruction of object nonharmonic motion function by diode laser signal operating in autodyne regime

摘要

The possibility of the reconstruction of a complex non-harmonic function of the moving object by means of autodyne interference system is represented in this work. The results of the experiment show the possibility to determine the parameters of complex nonharmonic movements of the reflector. It is obvious that the use of multistage digital filtering in the course of autodyne experiment allows us to reduce the influence of the noise distortion on restored signal.
