Abstract

This sensor is based on the optical coupling between two optical fibers, submitted simultaneously to the same constraint. Due to the geometrical deformations, photoelasticity, and evanescent field this coupling was studied theoretically and experimentally, and used to build a time multiplexed sensor network by coupling short pulses. This arrangement has high sensitivity and resolution, without some drawbacks of the classical OTDR.
