DISTRIBUTED ACOUSTIC SENSING THE NANO SCALE TECHNOLOGY

Distributed Acoustic Fiber Optic Sensing Technology

The sensitivity and speed of Rayleigh-based sensing allows distributed monitoring of acoustic signals over distances of more than 100 km from each laser source. Typical applications include continuous monitoring of pipelines for unwanted interference and for leaks or flow irregularities; monitoring of power cables for unwanted interference and cable faults; monitoring traffic (roads, railways and trains ), borders, and other sensitive perimeters for unusual activity; and even oil well monitoring applications. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device.
