Paper Abstract

A novel stable and high-sensitivity fiber strain sensor based on optical pulse correlation measurement and birefringence compensation approach is proposed. Both the differential correlation measurement and the double-path monitoring established in the birefringence compensation process provide the possibility of high-sensitivity sensing. By using the optical correlation strain sensing system, the strain characteristic of single-mode fiber and dispersion-shifted fiber with different coating materials at different length are investigated. The extension coefficients of the monitoring fibers are estimated. The results indicated that single-mode fiber with FRPE coating has the highest strain sensitivity in this experiment, which is potential to be used in the field measurement in future.
