Abstract
In this paper, we describe a sensor configuration based on optical coupling between two optical fibers submitted simultaneously to the same constraint. Theoretical and experimental results are reported on photoelasticity and the evanescent field of these coupled fibers due to geometrical deformations. Our purpose was to build a time multiplexed sensor network by coupling short pulses. This arrangement exhibits high sensitivity and resolution without any drawbacks of the classical OTDR.
