  • Apparatus and a method of locating a source of acoustic emissions in an article
    Patent number: 6065342
    Abstract: An apparatus (14) for locating a source of acoustic mission in an article (10) comprises a plurality of spaced transducers (18) which supply output signals corresponding to detected acoustic emission activity to a processor (24). Artificially induced acoustic emissions (12) are generated in the article (10) by directing a laser beam (33) onto the article (10). A camera (40) produces an image of the article (10) and any laser flashes. A processor (42) converts the positions of the laser flashes to coordinates on the article (10). A processor (24) analyses parameters of the acoustic emission in the output signals and the coordinates of the laser flashes to infer the mathematical relationship between the parameters and location of acoustic emissions.
