Paper Abstract

This paper reports on the results of a feasibility study concerning optical fiber Bragg grating sensors for vibration monitoring. The fiber grating sensors were embedded in glass-reinforced epoxy and graphite-reinforced PEEK active mount structures developed by the SPICES Consortium. The fiber sensors were interfaced to controllers by an acousto-optic tuned filter based instrument that provided simultaneous, real time, dynamic strain signals from 4 wavelength multiplexed sensors with a resolution of 0.002 microstrain per root Hz and a bandwidth of 4 kHz. The sensor interface design and performance are presented.
