  • Optical fiber surveillance topology
    Patent number: 8121442
    Abstract: In accordance with an aspect of the disclosed technology, a fiber surveillance system includes a single optical fiber, used, for example, in the detection of acoustic signals associated with vibrations or other activity. In one embodiment of the disclosed technology, the fiber is arranged in a two dimensional topology to improve the spatial resolution of the system. With such a topology the spatial monitoring resolution of the surveillance system is significantly improved over systems in which the fiber is deployed in an essentially straight line topology. In a further embodiment of the disclosed technology, two or more such oriented fibers are juxtaposed or overlapped to yield even greater resolution.
