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 ...
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 ...
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 ...
