Abstract: A method and apparatus for testing a composite structure. A pulsed laser beam having a number of properties is generated. Each of the number of properties is within a selected range. The pulsed laser beam generated by the generation laser system is directed towards a composite structure comprised of a number of composite materials. A number of ultrasonic waves are formed in the composite structure when the pulsed laser beam contacts the composite structure without causing any undesired inconsistencies in the composite structure outside of selected tolerances.

Abstract: A method and apparatus for inspecting a structure. In one illustrative embodiment, an apparatus comprises a laser system located outside of an area that includes a region of a structure to be inspected, a mobile platform located within the area to be inspected, and a projection system associated with the mobile platform. The laser system is configured to generate a laser beam. The projection system receives the laser beam and projects the laser beam onto a surface of the region of the structure. The laser beam causes a number of ultrasonic waves to form within the structure.
