Abstract:
The formation of an autodyne interference signal under the current modulation of the laser radiation wavelength is studied. For the first time we propose a method for determining the stationary phase of the autodyne signal based on the analysis of the lowfrequency spectrum of the laser autodyne system. The results of measuring nanodisplacements of the electromagnetic translator by the ratio of the autodyne signal spectral components under harmonic current modulation of the laser autodyne wavelength are presented.
Keywords:
laser interferometry, autodyne, semiconductor laser, laser radiation modulation, distance measurement, microvibration, spectral analysis of signals.
