A Code Division Design Strategy for Multiplexing Fiber Bragg Grating Sensing Networks

Triana-Infante, Cristian Andres; Pastor Abellán, Daniel; Varón, Margarita (MDPI AG, 2017)
Adhesive assisted fabrication of chirped POF Bragg grating

Min, Rui; Pereira, Luis; Paixao, Tiago; Woyessa, Getinet; André, Paulo; Bang, Ole; Frizera, Anselmo; Antunes, Paulo; Pinto, Joao; Li, Zhaohui; Ortega Tamarit, Beatriz; Marques, Carlos (SPIE, 2020-04-10)

[EN] FBG in polymer optical fibers (POFs) is a promising technology for a wide range of sensing applications due to a lower Young¿s modulus and a large range of applying strain. Furthermore, POFs have several properties ...
Characterization and calibration of shape sensors based on multicore optical fibre

Idrisov, Ravil; Floris, Ignazio; Rothhardt, Manfred; Bartelt, Hartmut (Elsevier, 2021-01)

[EN] In order to provide high accuracy in shape measurement with multicore optical fibres, characterization and calibration procedures are an important part of sensor preparation. Some procedures can be considered mandatory ...
Chirped POF Bragg grating production utilizing UV cure adhesive coating for multiparameter sensing

Min, Rui; Pereira, Luis; Paixao, Tiago; Woyessa, Getinet; Hu, Xuehao; Antunes, Paulo; André, Paulo; Bang, Ole; Pinto, João; Ortega Tamarit, Beatriz; Marques, Carlos (Elsevier, 2021-09)

[EN] In this work, we obtained chirped Bragg gratings by post-coating uniform poly (methylmethacrylate) (PMMA) microstructured polymer optical fiber Bragg gratings (POFBGs) with an UV cure adhesive. The main advantage of ...
Curvature, twist and pose measurements using fiber Bragg gratings in multi-core fiber: A comparative study between helical and straight core fibers

Khan, Fouzia; Barrera, David; Sales Maicas, Salvador; Misra, Sarthak (Elsevier, 2021-01-01)

[EN] This paper presents a technique to acquire measurements of curvature, twist and pose for two multi-core fibers; one with straight cores and the other with helical cores. Both the fibers have multiple fiber Bragg grating ...
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 ...
Magnetic actuator based on giant magnetostrictive material Terfenol-D with strain and temperature monitoring using FBG optical sensor

García Miquel, Ángel Héctor; Barrera Vilar, David; Amat, Rafael; Kurlyandskaya, G. V.; Sales Maicas, Salvador (Elsevier, 2016-02)

We have designed a temperature and strain monitoring system for a magnetic actuator based on the giant magnetostrictive material Terfenol-D (Tb0.3 Dy0.7Fe1.92) with Fiber Bragg grating (FBG) sensors. Magneto-elastic ...
Multi-Core Optical Fibers With Bragg Gratings as Shape Sensor for Flexible Medical Instruments

Khan, Fouzia; Denasi, Alper; Barrera, David; Madrigal-Madrigal, Javier; Sales Maicas, Salvador; Misra, Sarthak (Institute of Electrical and Electronics Engineers, 2019-07-15)

[EN] This paper presents a technique to reconstruct the shape of a flexible instrument in three-dimensional Euclidean space based on data from fiber Bragg gratings (FBGs) that are inscribed in multi-core fibers. Its main ...
Optical fiber sensors embedded in concrete for measurement of temperature in a real fire test

Bueno Martínez, Antonio; Torres Górriz, Benjamín; Barrera Vilar, David; Calderón García, Pedro Antonio; Lloris, J.; López, M.; Sales Maicas, Salvador (Society of Photo-optical Instrumentation Engineers (SPIE), 2011)

We present the results of a real fire test using optical fiber sensors embedded in concrete samples. The temperature curve used in this experiment is described in the Spanish/European standard UNE-EN 1363-1 temperature ...
Polymer optical fiber gratings for microwave photonics and communications application

Min, Rui (Universitat Politècnica de València, 2019-09-02)

[ES] Con el continuo desarrollo de materiales y tecnologías de fabricación durante las últimas tres décadas, la atenuación de la transmisión de las fibras ópticas de polímero (POF) se ha reducido considerablemente. Las POF ...
