Paper Abstract

This article has put forward a new optical fiber strain sensor, based on the spiral bending loss of single mode fiber. It uses the theory of backward Rayleigh scatter and anlong with OTDR composes of distributed fiber optic sensing system so as to realize the measurement at a certain precision. The paper has also proceeded the theory analysis and experimental investigation on the optical fiber sensing system, and has proved its good sensing characteristics.
