    Sensing Applications in Aircrafts Using Polymer Optical Fibres
    (MDPI, 2021-04-07) Contreras Lallana, Pedro; Aldabaldetreku, Gotzon; López, Alicia; Sánchez Montero, David; Durana, Gaizka; Mateo, Javier; Losada, María Ángeles; Zubia, Joseba; Vázquez García, Carmen
    We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for sensing applications in avionics. The sensors analysed in this manuscript take advantage of the unique properties of polymers, such as high flexibility, elasticity, and sensitivity, and they range from strain, elongation, and vibration interrogators to level and temperature meters, leading to cost-effective techniques for structural health monitoring in aircraft structures. We also highlight recent power-supply methods using Power-over-POF in order to feed sensors remotely, and we discuss the constraints imposed by connectors on the performance of POF networks in aircrafts.

    Temperature Sensing Using Optical Fibers in Harsh Environments
    (IEEE, 2017-09-04) Vázquez García, Carmen; Tapetado, Alberto; Pinzón, Plinio Jesús; Sánchez Montero, David; López Cardona, Juan Dayron; Contreras Lallana, Pedro; Zubia, Joseba
    Temperature is a major magnitude that needs to be measured in many different scenarios such as monitoring the temperature during manufacturing process, in aeronautical engine performance, or in all electrical aircraft batteries performance among others. Fiber optic temperature sensors have very interesting properties due to its potential to provide electromagnetic interference immunity, light weight, intrinsically safe nature, and depending on the technology high temperature range and remote operation. In this talk we will review our recent progress on intensity fiber-optic temperature sensing with different technologies and applications.
