High‐Order Fiber Bragg Grating Corrosion Sensor Based on the Detection of a Local Surface Expansion
Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces. In the proposed sensor design, a sensing fiber with an inscribed high‐order Bragg grating is attached to the observed metal surface. A broadening of high‐order Bragg grating spectral characteristics is observed and used to detect small and ...
