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