Effect analysis of external optical feedback on waveform and spectrum of semiconductor laser autodyne signal has been performed. The method of nanovibration amplitude determination has been described. The method involves measuring ratio of the first spectral components of nanovibration autodyne signal to one of the additional mechanical vibrations, taking into account the level of external optical feedback. It has been experimentally shown, that taking into account external optical feedback can significantly improve the accuracy of nanovibration measurements.
