Fiber optic delamination sensors detect structural damage by monitoring strain variations along the fiber embedded in or attached to a composite material. Delamination or interfacial debonding alters the local strain distribution, which can be measured as a change in the integrated strain along the fiber. Interferometry-based sensors detect these small strain changes by measuring phase shifts in light traveling through the fiber, while FBG sensors detect shifts in reflected wavelength caused by strain changes in the fiber core .
Fiber optic delamination sensors are widely used in aerospace, civil engineering, and composite material research to monitor structural integrity, detect early-stage damage, and guide maintenance decisions. They enable non-destructive evaluation and continuous structural health monitoring, improving safety and reducing inspection costs.
