Design and fabrication of customized fiber gratings to improve the interrogation of optical fiber sensors

Ricchiuti, Amelia Lavinia (Universitat Politècnica de València, 2016-06-23)

[EN] Fiber grating sensors and devices have demonstrated outstanding capabilities in both telecommunications and sensing areas, due to their well-known advantageous characteristics. Therefore, one of the most important ...
Effects of bonding on the performance of optical fiber strain sensors

Floris, Ignazio; Sangiorgio, Valentino; Adam, Jose M; Uva, Giuseppina; Rapido, Monica; Calderón García, Pedro Antonio; Madrigal-Madrigal, Javier (John Wiley & Sons, 2021-09)

[EN] The structural health monitoring (SHM) of existing buildings, structures, and infrastructures has become increasingly important in recent years, while the interest of the scientific community is focused on the use of ...
Effects of core position uncertainty on optical shape sensor accuracy

Floris, Ignazio; Calderón García, Pedro Antonio; Sales Maicas, Salvador; Adam, Jose M (Elsevier, 2019-06)

[EN] Optical fiber sensors are now widely recognized as extremely reliable instruments to sense strain. Optical shape sensors consist of multiple single-core optical fibers or multicore optical fibers capable of sensing ...
Experimental study of the influence of FBG length on optical shape sensor performance

Floris, Ignazio; Madrigal-Madrigal, Javier; Sales Maicas, Salvador; Adam, Jose M; Calderón García, Pedro Antonio (Elsevier, 2020-03)

[EN] This paper compares the performance of optical Multicore Fibres (MCFs) with inscribed Fibre Bragg Gratings (FBGs) used as curvature and shape sensors in relation to strain sensor length. Two fibre optic shape sensors, ...
Fiber Optic Refractive Index Distributed Multi-Sensors by Scattering-Level Multiplexing With MgO Nanoparticle-Doped Fibers

Ayupova, Takhmina; Shaimerdenova, Madina; Korganbayev, Sanzhar; Sypabekova, Marzhan; Bekmurzayeva, Aliya; Blanc, Wilfried; Sales Maicas, Salvador; Guo, Tuan; Molardi, Carlo; Tosi, Daniele (Institute of Electrical and Electronics Engineers, 2020-03-01)

[EN] In this work, we present the architecture of a multiplexed refractive index (RI) sensing system based on the interrogation of Rayleigh backscattering. The RI sensors are fabricated by fiber wet-etching of a high-scattering ...
Twisting measurement and compensation of optical shape sensor based on spun multicore fiber

Floris, Ignazio; Madrigal-Madrigal, Javier; Sales Maicas, Salvador; Calderón García, Pedro Antonio; Adam, Jose M (Elsevier, 2020-06)

[EN] This study presents a novel method for twisting compensation in optical shape sensing and first reports on twisting sensing by using Fiber Bragg Gratings (FBG) inscribed in a spun Multicore Fiber (MCF). A simple ...
