Optical Fiber Sensors for Aircraft Structural Health Monitoring
(MDPI, 2015-06)
Aircraft structures require periodic and scheduled inspection and maintenance operations due to their special operating conditions and the principles of design employed to develop them. Therefore, structural health monitoring ...
Theoretical Modeling of Viscosity Monitoring with Vibrating Resonance Energy Transfer for Point-of-Care and Environmental Monitoring Applications
(MDPI, 2018-12-21)
Forster resonance energy transfer (FRET) between two molecules in nanoscale distances is utilized in significant number of applications including biological and chemical applications, monitoring cellular activities, sensors, ...
Simultaneous Sensing of Refractive Index and Temperature With Supermode Interference
(IEEE, 2021-11-15)
[EN]In general, a sensor is used to monitor a single parameter only, and in many cases, a reference sensor is necessary to compensate the effect of temperature. Here, we demonstrate that a single supermode interferometer ...
High-performance vector bending and orientation distinguishing curvature sensor based on asymmetric coupled multi-core fibre
(Nature, 2020-08-20)
Fibre optic technology is rapidly evolving, driven mainly by telecommunication and sensing applications. Excellent reliability of the manufacturing processes and low cost have drawn ever increasing attention to fibre-based ...
Accurate Strain Sensing Based On Super-Mode Interference In Strongly Coupled Multi-Core Optical Fibres
(Nature Publishing Group, 2017-06-30)
We report on the use of a multi-core fibre (MCF) comprising strongly-coupled cores for accurate strain sensing. Our MCF is designed to mode match a standard single mode optical fibre. This allows us to fabricate simple MCF ...
Sensitivity magnification of an interferometric optical fiber sensor with a length-linked virtual reference
(Elsevier, 2023-12)
Here, it is proposed an alternative to magnify the sensitivity of a single optical fiber interferometric sensor up to two orders of magnitude. The method consists of fabricating the sensing interferometer with a specific ...
Packaged multi-core fiber interferometer for high temperature sensing
(IEEE, 2019-03-07)
[EN]A small size and compactly packaged optical sensor for high-temperature measurements is reported. The sensor consists of a short piece of multi-core fiber (MCF) spliced to the distal end of a single-mode fiber. The ...
Accurate microthermometer based on off center polymer caps onto optical fiber tips
(Elsevier, 2018-05-26)
We report on microscopic polymer spherical caps bonded onto the cleaved end of a single-mode fiber (SMF) for
fast, accurate, and sensitive temperature sensing. The microcaps were fabricated by dispensing sub nano-liter
amounts ...
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
(Elsevier, 2021-07)
The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ...
