Abstract :
This paper discusses the used of an optical interferometry technique for bending and torsional vibrational modes measurement. With this technique, the amplitude and frequency of the vibrations involved in tabletop of a home-made optical table were measured. Besides, vibrational modes involved and performance of the damping system were determined.
