Abstract
A method and apparatus for inspecting a test object. The apparatus comprises an inspection vehicle, a sensor structure, a first array of optical fibers, and a second array of optical fibers. The inspection vehicle is configured to move on a surface of the test object. The sensor structure is associated with the inspection vehicle. The first array of optical fibers is associated with the sensor structure. The first array of optical fibers is configured to transmit a pattern of light towards the surface of the test object and the pattern of light is configured to cause sound waves in the test object when the pattern of light encounters the test object. The second array of optical fibers is associated with the sensor structure. The second array of optical fibers is configured to detect a response to the sound waves.
