In-Titanium Embedded Multiplexed Femtosecond Fiber Bragg Gratings under Intense Heat Flow - Comparison between Experimental and Numerical Heat and Strain Cartography

Optical fiber sensors received a large interest in the past decades thanks to key advantages such as high temperature resistance, insensitivity to electromagnetic perturbation, and a low intrusivity allowing an efficient integration into metallic parts [1]… In the aeronautical context, aircraft structures can be exposed to large temperature variation as well as high acceleration and vibration levels. Optical fiber sensors are good candidates to monitor under such environments.
