Abstract
A system and method for detecting structural damage in a layered structure, the method compromising: providing an array of optical fibers attached to the layered structure; providing a laser source for emitting light into the optical fibers; providing a thermal imaging device; transferring laser light beam through each of the optical fibers of the array; acquiring at least one thermal image of an external surface of the layered structure; and detecting existence of one or more hot spots on the external surface indicative of a location of damage in the layered structure.
