Fiber optic sensors for sonar

Distributed Acoustic Sensing (DAS) technology transforms ordinary fiber-optic cables into expansive acoustic sensors. By transmitting a pulsed laser through the cable, DAS can identify tiny backscattered signals that change due to vibrations or stress from nearby sound waves. Undersea fiber-optic cables, initially designed for communication, are now being...
