Microbend Point and Distributed Fiber Optic Corrosion Sensing

Corrosion-induced optical fiber microbending is demonstrated within this article as an efficient method for the design of sensors for the detection and localization of corrosion events on monitored metal surfaces. The proposed sensors were demonstrated in a single point and fully distributed configurations while applied successfully on bare metal surfaces and underneath corrosion-protective coatings. The intrinsic simplicity in the design and manufacturing of the proposed sensors, reliable corrosion detection, and corrosion localization are the main attributes of the proposed microbend corrosion sensing concept.
