acoustic sensor
A standard single-mode optical fiber (G.652) is used as a sensitive element. The optical fiber is connected to the hardware unit which is continuously monitoring vibro-acoustic events along the optical fiber line.

About the system
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.
