Abstract
In laser Doppler vibrometry of sinusoidal vibration, direct analysis of the photodetector output or the heterodyne signal using a spectrum analyzer is emphasized. A technique utilizing the spectra at the carrier frequency and the first sideband is proposed for unambiguous analysis of the vibration amplitude. Experimental results demonstrate the validity of the proposed technique.
