OverviewFundamentals of Rayleigh scatter-based fiber optic sensingCapabilities of Rayleigh-based systemsComparison with other fiber optic distributed sensing techniquesApplications
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.
