Perimeter detection using fiber optic sensors |
摘要 |
A fiber optic perimeter detection system includes a receiver to receive output light signals from sensors positioned at different regions, each sensor including a sensing fiber. Each sensor generates an output light signal having a specified wavelength, the output light signal having a property that varies when stress is induced in the sensing fiber. The perimeter detection system includes a memory to store information related to a mapping between the wavelengths of the output light signals and the regions where the sensors are positioned.
