摘要:
A method and apparatus for testing a composite structure. A pulsed laser beam having a number of properties is generated. Each of the number of properties is within a selected range. The pulsed laser beam generated by the generation laser system is directed towards a composite structure comprised of a number of composite materials. A number of ultrasonic waves are formed in the composite structure when the pulsed laser beam contacts the composite structure without causing any undesired inconsistencies in the composite structure outside of selected tolerances.
摘要:
The invention relates to a method 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.
摘要:
A method and apparatus for generating a tension wave (868). A beam of coherent light (864) is directed to an absorber surface (847) of a transducer structure (842). A compression wave (872) is generated within the transducer structure (842). The compression wave (872) is reflected on a reflecting surface (846) of the transducer structure (842) to form the tension wave (868). The tension wave (868) is directed through a test object (810) in a desired direction (867) using a configuration of the reflecting surface (846) relative to the test object (810).
