Abstract
A microphone array for detecting acoustic emissions generated by equipment. The array includes at least one grid having a plurality of sensors each including a compact arrangement of optical fiber having first and second optical fiber ends wherein the first optical fiber end of a first sensor is terminated. The array also includes an optoelectronic device coupled to a second optical fiber end of a second sensor, wherein the optoelectronic device generates laser light that is transmitted through the plurality of sensors in the grid and is reflected back to the optoelectronic device to enable detection of acoustic emissions.
