Paper Abstract

A Michelson based fiber optic low-coherence interferometric quasi-distributed sensing system permitting absolute length measurement in the sensors array is proposed. The main part of the sensing system is a fiber optic 3x3 star coupler. The architecture of the fiber optic sensors can be easy realized as a linear sensor array, twin sensor arrays or a loop sensor array. The proposed sensing scheme will be useful for the measurement of strain distribution. An important application could be deformation sensing in smart structures. Experimentally, a 6 sensors array has been demonstrated.
