Abstract: A method for and apparatus for inspecting a location on a test object with a number of obstructions to reaching the location. An elongate optical fiber carrier holding a number of optical fibers is moved to the location on the test object with the number of obstructions to reaching the location. A pattern of light is transmitted from the number of optical fibers onto a surface of the test object at the location. The pattern of the light is configured to cause sound waves in the test object when the pattern of the light encounters the surface of the test object. A response is detected to the sound waves using the number of optical fibers.

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.

Abstract: A system for inspecting a test article incorporates a diagnostic imaging system for a test article. A command controller receives two dimensional (2D) images from the diagnostic imaging system. A three dimensional (3D) computer aided design (CAD) model visualization system and an alignment system for determining local 3D coordinates are connected to the command controller.

Abstract: An ultrasonic data analysis and display system for use with ultrasonic test apparatus. The ultrasonic analysis and display system includes a display that is divided into six different display formats, including a pulse echo, a time of flight display, an A-Scan, a horizontal and vertical B-Scan, and a control display. Each of the displays gives a different view of the ultrasonic test data obtained from a test part. When a portion of the ultrasonic data in any of the display formats is selected, the other display formats are automatically updated to reflect the operator's selections. The format of the displayed data can be changed to a half-wave positive, a half-wave negative, or a full-wave rectification. Distances within any of the display formats can be measured by selecting two data points.
