Dynamic demodulation of spectral shifts in fiber-Bragg-grating sensors

Research output: Contribution to journalArticle

Abstract

Fiber-optic sensors are receiving significant attention in structural-health monitoring (SHM) of large-scale structures. They allow for on-board diagnostic monitoring of a structure's damage state and its dynamic response to changing environmental conditions. In particular, these sensors offer attractive, on-demand assessment capabilities for monitoring structural changes in safety-critical complexes such as bridges and aircraft.
