Dynamic curvature sensing using time expanded (Phi)OTDR
[EN] Shape sensing can be accomplished using optical fiber sensors through different interrogation principles such as fiber Bragg gratings, optical frequency-domain reflectometry (OFDR), or optical time-domain reflectometry (OTDR). These techniques are either not entirely distributed, have poor performance in dynamic sensing, or are only valid for few-meter-long fibers. Here, we present a system able to perform distributed curvature sensing with a range of 125 m, 10-cm resolution, and a sampling rate of 50 Hz. This is done by interrogating three cores of a multi-core fiber (MCF) with the novel, to the best of our knowledge, time-expanded phase-sensitive (TE-¿)OTDR technique. This system fills a performance gap in fiber shape sensors, opening the door to applications in civil engineering, medicine, or seismology. ; MCIN/AEI and FSE Invierte en Tu Futuro (PRE2019 087444); MCIN/AEI and European Union NextGenerationEU /PRTR (RYC2021-032167-I, RYC2021-035009-I); MCIN/AEI (I+D+i project INSTILL PID2020-120071RJ I00); Comunidad de Madrid and FEDER Program (SINFOTON2-CM: S2018/NMT-4326); Spanish MCIN/AEI and the European Union NextGenerationEU/PRTR Program (PSI PLEC2021- 007875, TREMORS CPP2021-008869); FEDER Una Manera de Hacer Europa (PID2021-128000OB-C21, PID2021-128000OB-C22); European Innovation Council (SAFE: 101098992). ; Escobar-Vera, C.; Soriano-Amat, M.; Martins, HF.; Barrera Vilar, D.; Martín-López, S.; Gonzalez-Herraez, M.; Fernández-Ruiz, MR.
