This work is focused on a review of three types of distributed optical fiber sensors which are based on Rayleigh, Brillouin, and Raman scattering, and use various demodulation schemes, including optical time-domain reflectometry, optical frequency-domain reflectometry, and. Distributed Fiber Optic Sensing (DFOS) transforms standard fiber cables into distributed arrays capable of measuring strain, temperature, vibration, and pressure by analyzing backscatter patterns in laser pulses transmitted along the cable. Although much of the initial development of these sensors was technology-driven, the most successful examples of fiber sensors are those where one or more of the often-cited benefits of fiber senso s bring a fundamental advantage to a.
