Fiber Bragg Grating (FBG) Sensors in a High-Scattering Optical Fiber Doped with MgO Nanoparticles for Polarization-Dependent Temperature Sensing

Molardi, Carlo; Tiago, Paixao; Beisenova, Aidana; Min, Rui; Paulo, Antunes; Marques, Carlos; Blanc, Wilfried; Tosi, Daniele (APPLIED SCIENCES-BASEL, 2019-08-01)

The characterization of Fiber Bragg Grating (FBG) sensors on a high-scattering fiber, having the core doped with MgO nanoparticles for polarization-dependent temperature sensing is reported. The fiber has a scattering level ...
PERFORMANCE ANALYSIS OF SCATTERING-LEVEL MULTIPLEXING (SLMUX) IN DISTRIBUTED FIBER-OPTIC BACKSCATTER REFLECTOMETRY PHYSICAL SENSORS

Tosi, Daniele; Molardi, Carlo; Blanc, Wilfried; Paixão, Tiago; Antunes, Paulo; Marques, Carlos (MDPI, 2020-05)

Optical backscatter reflectometry (OBR) is a method for the interrogation of Rayleigh scattering occurring in each section of an optical fiber, resulting in a single-fiber-distributed sensor with sub-millimeter spatial ...
