Recent Advancement in Optical Fiber Sensing for Aerospace Composite Structures

Optical fiber sensors have attracted considerable attention in health monitoring of aerospace composite structures. This paper briefly reviews our recent advancement mainly in Brillouin-based distributed sensing. Damage detection, life cycle monitoring and shape reconstruction systems applicable to large-scale composite structures are presented, and new technical concepts, ＂smart crack arrester＂ and ＂hierarchical sensing system＂, are described as well, highlighting the great potential of optical fiber sensors for the structural health monitoring （SHM） field.
