    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.

    Abstract: A method for testing a structure includes steps of: identifying a three-dimensional position of a surface of the structure relative to a reference frame; transmitting laser light from an output of a transmitter onto the surface of the structure to form ultrasonic waves in the structure and to detect a response to the ultrasonic waves; based on the three-dimensional position of the surface, moving the laser light over the structure along a scan path so that the output of the transmitter is located at a constant offset distance from the surface and that the laser light, transmitted from the output of the transmitter, is directed onto the surface at a constant angle of projection; and based on the response to the ultrasonic waves, determining whether an inconsistency is present in the structure.

    Abstract: A method of detecting inconsistencies in a composite structure is presented. A pulsed laser beam is directed towards the composite structure comprised of a number of composite materials. Wide-band ultrasonic signals are formed in the composite structure when radiation of the pulsed laser beam is absorbed by a surface of the composite structure. The wide-band ultrasonic signals are detected over a duration of time to form data. The data comprises an ultrasonic A-scan spectrum. The data is processed to identify a structure signal in a frequency domain of the ultrasonic A-scan spectrum. The structure signal of the ultrasonic A-scan spectrum is compared to a structure signal of a composite structure standard to determine whether the inconsistencies are present in the number of composite materials.

    Abstract: Method and apparatus for enabling ultrasonic inspection of a changing, insufficiently defined or unknown shape (e.g., a variable radius or a noncircular radius caused by the use of soft tooling) at a rate that meets production requirements. The apparatus comprises a linear ultrasonic array (i.e., sensor) incorporated in a toppler, which in turn is slidably supported by an oscillating sensor mechanism carried by a traveling trailer vehicle. As a result of this arrangement, the sensor can undergo a back-and-forth sweeping motion coupled with motion along the spar radius. The sensor is further able to displace radially relative to a sweep pivot axis and rotate (hereinafter “topple”) about a topple pivot axis. In this manner, the orientation of the sensor can adjust to the contour of the inspected surface as the sensor scans.
