Rayleigh scattering based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. Such a system allows acoustic frequency strain signals to be detected over large distances and in harsh environments. WebAcoustic emission measurements are best performed with optical fiber technology, since it is highly sensitive and can measure with extremely low noise in exceptionally harsh …
