摘要： A method and apparatus for generating a tension wave. A beam of coherent light is directed to an absorber surface of a transducer structure. A compression wave is generated within the transducer structure. The compression wave is reflected on a reflecting surface of the transducer structure to form the tension wave. The tension wave is directed through a test object in a desired direction using a configuration of the reflecting surface relative to the test object.

摘要： A method and apparatus for multi-energy object inspection using a brilliant x-ray source. A first mono-energetic x-ray image of an object at a first selected energy is generated. A second mono-energetic x-ray image of the object at a second selected energy is generated. The first selected energy is different than the second selected energy. Additional mono-energetic x-ray images may be generated at energies different than previous energies up to n selected energies. The mono-energetic x-ray images are mathematically combined and processed to form a result. The result of processing the mono-energetic x-ray images is presented. The result comprises processed mono-energetic x-ray image data describing materials in the object with greater sensitivity, identifying the layers, and identifying the material composition than in the first image or the second image.

摘要： An ultrasonic stimulus pulse is emitted incident to a laminar structure and recorded as pulse data. Echoes resulting from the stimulus pulse are recorded as echo data. One or more vectors are derived by way of time-shifting the recorded pulse data by respective amounts and a matrix Φ is defined including the one or more vectors. An echo vector Y is defined using the recorded echo data. A solution vector X is determined in accordance with: Y=Φ*X, typically within a predetermined tolerance. B-scan display or other analysis of one or more distinct solution vectors enables user and/or automated identification and measurement of any anomalies within the laminate material.

摘要： 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.
