About the system

The system operation is based on the principle of coherent reflectometry. Optical pulses are repetitively sent into the monitored fiber, where a very small fraction of light is backscattered due to material non-uniformities. Fiber microdeformations caused by seismo-acoustic signals affects this backscattered signal. The signal changes are continuously monitored and analyzed to identify the location and specifics of the vibro-acoustic event detected by the fiber.
