Abstract :
Traditionally, small amplitude vibrations are measured with the Michelson interferometer in discrete amplitude values. This paper extends this measuring method for amplitudes lying in continuous intervals. The verification of the theory was made in the case of a vibrating quartz crystal. The analysis of the experimental results leads to the conclusion that this method can be used for vibration measurements with nm amplitude
