Method for embedding optical fibers and optical fiber sensors in metal parts and structures
Abstract
A technique for embedding one or more optical fibers in a cast metal part or structure while maintaining optical transmission through the fiber is presented. This technique provides a nondestructive monitor of internal perturbations of the structure. Application of the method to embedded fiber optic sensors in metallic structures and to fiber-embedded metal feedthrough are reported, and the performances of temperature and ultrasound fiber sensor embedded in a cast aluminium block are demonstrated.
