Abstract:
A multiplexed white light interferometric fiber optic twinsensorarray was designed to monitor the structural health of large buildings. In this sensing system, based on a Michelson interferometer, an optical path matching technique is used to demodulate each twinsensor. Each twinsensorarray consists of a 2×N sensing element linked by a 3 dB coupler. When one of the twinsensor is used to measure strain, variations caused by temperature can be compensated for by referencing the other twinsensor. The multiplexing capacity of the sensing scheme has been analyzed and experimental results with a 2×3 twinsensorarray are given.
