Abstract:

A fiber optic sensor system includes a first optical power source which injects a light pulse into an optical fiber loop system. The light pulse circulates in the optical fiber loop system at a circulation frequency. The optical fiber loop system includes a transducer which modulates the circulation frequency in response to detecting a changing physical condition, a filter, polarization controller, an isolator, and an optical fiber gain medium for amplifying the light pulse. A second optical power source provides optical energy to the optical fiber gain medium. A detector system transforms a portion of the light pulse received from the optical fiber loop system into an output signal representing the circulation frequency.
