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. ABSTRACT: Sensing arrays developed from interpreting the interaction of laser pulses within fiber optics revolutionize how we measure and assess natural and built environments. Fiber-optic-based measurement techniques monitor temperature, strains, and vibration with arrays as long as tens of.
