Non-Destructive Testing, 1974
Abstract This final paper in the series on acoustic emission deals with existing industrial applications of this technology. Such applications have increased greatly in recent years and now include such areas as weld monitoring, monitoring of proof tests on structures and components, and the detection and location of flaws in pressure vessels.

An acoustic-emission sensor includes a composite synthetic resin-ceramic piezoelectric element which has a plurality of substantially mutually parallel columnar ceramic piezoelectric bodies. The columnar ceramic piezoelectric bodies are polarized in a longitudinal direction and are disposed in a synthetic-resin matrix. Since only longitudinal waves can

A periodic structure such as a diffraction grating is disposed on the surface of an object from which acoustic emissions are to be detected. A plane monochromatic light beam is incident on the periodic structure and forms a number of Bragg diffraction orders at predetermined angles.
