Abstract
A distributed fiber-optic stress sensor by synthesis of the optical coherence function is proposed. This system can obtain polarization coupling distribution in a polarization maintaining fiber due to lateral stress, using neither mechanical moving parts nor further calculations. In experiments, the spatial resolution of about 9 m and the measurable range of about 1040 m are demonstrated.
