Harnessing Deep-Hole Drilling to Fabricate Air-Structured Polymer Optical Fibres
(MDPI, 2019-10-24)
The performance of a precisely controlled drilling technique is critical in the fabrication process of microstructured polymer optical fibres. For the creation of a holey preform, adequate drilling bits with large ...
Miniature interferometric humidity sensor based on an off-center polymer cap onto optical fiber facet
(Elsevier, 2019-06-17)
In this work, we propose an interferometric humidity sensor based on a polymer micro-cap bonded off-center on the polished end of a standard single mode fiber (SMF). In our sensor, the sensitive part is the micro-cap. In ...
Miniature interferometric humidity sensor based on an off-center polymer cap onto optical fiber facet
(Elsevier, 2019-09-15)
In this work, we propose an interferometric humidity sensor based on a polymer micro-cap bonded off-center on the polished end of a standard single mode fiber (SMF). In our sensor, the sensitive part is the micro-cap. In ...
Composed multicore fiber structure for direction-sensitive curvature monitoring
(2020-07-01)
The present work deals with a curvature sensor that consists of two segments of asymmetric multicore fiber (MCF) fusion spliced with standard single mode fiber (SMF). The MCF comprises three strongly coupled cores; one of ...
Sensing Applications in Aircrafts Using Polymer Optical Fibres
(MDPI, 2021-05-21)
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 ...
Tip-Clearance Measurement in the First Stage of the Compressor of an Aircraft Engine
(MDPI, 2016-11-11)
In this article, we report the design of a reflective intensity-modulated optical fiber sensor for blade tip-clearance measurement, and the experimental results for the first stage of a compressor of an aircraft engine ...
Optical Tip Clearance Measurements as a Tool for Rotating Disk Characterization
(MDPI, 2017-01)
An experimental investigation on the vibrational behavior of a rotating disk by means of three optical fiber sensors is presented. The disk, which is a scale model of the real disk of an aircraft engine, was assembled in ...
Compact Omnidirectional Multicore Fiber-Based Vector Bending Sensor
(Nature, 2021-03-16)
We propose and demonstrate a compact and simple vector bending sensor capable of distinguishing any direction and amplitude with high accuracy. The sensor consists of a short segment of asymmetric multicore fiber (MCF) ...
A method for the controllable fabrication of optical fiber-based localized surface plasmon resonance sensors
(Nature, 2022)
[EN] Optical fiber-based Localized Surface Plasmon Resonance (OF-LSPR) biosensors have emerged as an ultra-sensitive miniaturized tool for a great variety of applications. Their fabrication by the chemical immobilization ...
