DAS- Distributed Acoustic Sensing

Reservoir Group's DAS system detects minute changes to the path of light caused by sound waves hitting and altering the structure of the optical fiber.

Reservoir Group's DAS system detects minute changes to the path of light caused by sound waves hitting and altering the structure of the optical fiber.  The DAS system continuously monitors as it passes through the fiber and can detect changes anywhere along its length at a spatial resolution of 1 meter.  The sound waves could be the result of direct mechanical noise or any acoustic disturbance in the vicinity of the fiber. As noises or vibrations reach the fiber, they create an intrinsic property change and alter the phase of the backscatter from the laser pulses.das-distributed-acoustic-sensing
