摘要:
A hybrid inspection system and method are provided which utilize both an air-coupled transducer and a liquid-coupled transducer in order to enjoy the advantages offered by both types of transducers. The hybrid inspection system may include a first probe that includes the air-coupled transducer, such as a capacitive machined ultrasonic transducer, which is configured to emit ultrasonic signals and to air couple the ultrasonic signals into a workpiece. The hybrid inspection system may also include a second probe that includes the liquid-coupled transducer, such as a piezoelectric transducer, configured to receive the ultrasonic signals emitted by the air-coupled transducer of the first probe via a liquid coupling between the transducer and the workpiece.

摘要:
For inspecting a structure with non-destructive x-ray inspection, probes are magnetically coupled to opposing surfaces of the structure. An inspection device may be autonomous with a feedback-controlled motor and/or a positional encoder. An inspection device may include wireless operation for at least one probe. A display may be included to provide real-time visual images from an x-ray detector or an optical imager.
摘要:
A method and apparatus for inspecting a test object with a non-planar feature. A pattern of light is transmitted from a first array of optical fibers associated with a sensor structure onto a surface of the test object at a location of the non-planar feature. The pattern of light is configured to cause sound waves in the test object when the pattern of light encounters the test object. A response to the sound waves is detected using a second array of optical fibers associated with the sensor structure. A determination is made as to whether an inconsistency is present in the test object at the location of the non-planar feature from the response to the sound waves detected using the second array of optical fibers.

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.

摘要:
A patch and associated methods for monitoring and inspecting a structure are provided in order to facilitate such inspections. The patch includes a sheet of material configured to be attached to the structure and a frequency steerable array carried by the sheet of material. The frequency steerable array includes a plurality of sources for emitting structural waves in response to an input having a variable frequency such that variations in the frequency of the input cause the structural waves emitted by the plurality of sources to be controllably steered relative to the sheet of material. Methods utilizing one or more frequency steerable arrays for monitoring and inspecting a patch-repaired structure are also provided.

An inspection apparatus may include an arm member, a vacuum pump, a contact member, and at least one probe. The contact member may be connected to the arm member and connected to the vacuum pump for contacting and applying vacuum pressure from the vacuum pump to a workpiece surface being inspected. The at least one probe may be connected to the arm member for emitting signals against the workpiece surface being inspected and for receiving signals from the workpiece surface being inspected.
