Abstract

Conventional fiber optic interferometers are playing an important role as sensors for their high sensitivity, fast response and simple construction. However, they face the challenges of temperature stability and sensitive lead in/out disturbance. In this paper, we proposed a novel two-core fiber interferometric (TCFI) strain sensor, which utilizes the strain induced phase difference between the two cores for strain measurement and a polarization effect to obtain high S/N ratio and stability; also, we give experimental results. The experimental results are generally in accordance with the theory. Interferometric sensors of such kinds may have wide applications in the future
