DAS fiber optic sensing acoustic waves
Distributed Acoustic Sensing (DAS) systems detect strain changes and vibrations along optical fibers. This highly sensitive technology is used for monitoring critical infrastructure such as power cables, pipelines, or railroad tracks. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device.

Principles of Fiber Optic Acoustic Sensors
Distributed acoustic sensing relies on light which is Rayleigh backscattered from small variations in the of the fiber. The backscattered light has the same frequency as the transmitted light. There are a number of other distributed fiber sensing techniques that rely on different scattering mechanisms and can be used to measure other parameters. Brillouin scatter occurs due to the interaction between the light and acoustic travelling in the fiber. As the light is scattered by a.
