Abstract: A new method to measure subsonic vibrations of very small amplitude is presented. It makes use of an interferometric system plus a phase modulation of the laser light source. The accuracy is limited only by the shot noise of the laser. Some considerations are reported concerning the frequency spectrum of the signal and the signal to noise ratio. The experimental results show a good agreement with theory.
