Paper Abstract

A low-cost optical sensing system to measure vibrations up to high frequencies (40 kHz) is presented and validated with experiments. The developed system uses a sensing head made with plastic optical fibers to illuminate the vibrating surface and collect the reflected light; a non-demanding data processing is used to measure the amplitude and frequency of the vibration and to compensate the reflectivity of the vibrating surface. Preliminary measurements, performed on vibrating targets with different surface reflectivity have been performed to assess the performance of the system.
