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.
