"Light scattering in nanoparticles doped optical fibers, an opportunity"

Distributed sensing, based on Rayleigh scattering or arrays of reflectors, can be extended as a multi-fiber, multi-sensor technique by using multiplexing features. Current research has overcome the time-and wavelength-division multiplexing, that has represented the golden standard for fiber Bragg gratings. During this presentation, we introduce a novel domain that allows “parallel” multiplexing applied to distributed sensors, and are routed in the use of specialty fibers. The use of nanoparticles doped optical fibers enables new domains for multiplexing, that are discussed during this presentation. Scattering-level, polarization, and sensitivity-based multiplexing are discussed and applied to strain, temperature, 3D-shape and refractive index measurements.
