| Title: | Locating acoustic emission with an amplitude-multiplexed acoustic sensor array based on a modified Mach-Zehnder interferometer | Authors: | Gong, JM MacAlpine, M Jin, W Liao, YB |
Issue Date: | 1-Dec-2001 | Source: | Applied optics, 1 Dec. 2001, v. 40, no. 34, p. 6199-6202 | Abstract: | We report on an amplitude-division-multiplexed interferometric sensor array for locating acoustic emission. Preliminary experiments were carried out with a modified Mach-Zehnder interferometer consisting of two sensing arms and a reference arm and demonstrated a one-dimensional location accuracy of a few centimeters. The system can be extended for two- and three-dimensional location of acoustic emissions by the addition of one or two more sensing arms, respectively, in the interferometer. | Keywords: | Acoustic emission testing Electromagnetic fields Interferometers Light sources Multiplexing Oil filled transformers |
