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 ...
Design, Fabrication and Testing of a High-Sensitive Fibre Sensor for Tip Clearance Measurements
