Résumé

Distributed sensors allow for the measurement of different physical parameters (temperature, deformations, vibrations, etc.) along large distances. All of them employ scattering phenomena (Rayleigh, Brillouin, Raman) produced during the light propagation along the optical fibers. The present work will focus on the phase-sensi- tive OTDR, commonly used for detection and characterization of vibrations. These measurements, realized along tens of kilometers, permit the surveillance of large perimeters and civil infrastructures. It will be introduced a recent progress in this technology, which allows for distributed acoustic measurements using chirped pulses.
