Aircraft in active service are mostly made of aluminum alloy. On line health monitoring of these structures is becoming more important as the older aircraft reach the end of their design life. At the same time newer aircraft made of new materials such as composites need monitoring since the design methodology for these materials is still under development. While conventional NDT methods are improving, an on-line monitoring system would provide regular check-ups without significant downtime. Fiber optic sensors embedded into or mounted on the surface of materials or structures to monitor the integrity of members has been discussed widely in recent years. Among them the fiber optic polarimetric sensor (FOPS) has the advantage of long sensing gauge length. In the paper, FOPS are mounted on the surface of aluminum specimens as well as embedded within composites to demonstrate its ability to monitor the development of cracks and predict the residual load of the structures.
