Paper Abstract

An optical fiber vibration sensor designed for monitoring a fixed vibration frequency (in particular 100 Hz) is presented. The device utilizes multimode PCS optical fibers and graded-index microlenses in order to detect cantilever displacements induced by vibrations. A suitable signal processing provides a down-lead insensitive response. Design details of the optoelectronic system and experimental results are presented.
