Abstract:

FIBLOC denotes a fiber optic intrusion location sensor system, it is based on a U.S. patent held by ANRO Engineering, Inc., and the FIBLOC trademark has been allowed. The physical basis of the sensor rests on the phase sensitive interference phenomena which govern propagation of an off-axis opticalinfrared beam through a graded index fiber. A demonstration FIBLOC system, 100 meters in length and capable of localizing points of intrusion within 10 meters was constructed. The processor yields negligible false alarm rates and applies signal discriminants to identify the likely intruder as runner, walker or crawler. The system is ready for Phase III application and commercial development. Intrusion detection, Fiber optic intrusion sensor, Perimeter protection, Intruder location and classification
