Paper Abstract

The theory and experiment results of fiber optic vibration sensor based on over-coupled fused coupler (OCFC) is described, 2 novel scheme to form single-end sensor is presented, i.e. OCFC sensor with a reflection mirror and OCFC fiber loop sensor, the transmission spectrum of these OCFC sensor when applied with different strains is investigated and interrogation system is developed, the output of these sensors when applied with vibration and shock is shown. We demonstrate that the OCFC fiber loop sensor is feasible to have practical use to measure vibration signal because the sensor is easy to be fabricated, it has good low and high frequency response and the interrogation system is simple, low cost.
