In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain. Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. Fiber optic vibration sensors that use existing fiber optic cables laid for communication have the advantage of being able to collectively and accurately measure vibrations over a wide range along the cables1), 2), and in recent years, they have been attracting attention as a means of environmental. The ability to easily and economically acquire and synchronize multiple high-precision fiber optic accelerometer measurements brings the benefits of fiber optic sensing to a wid ding precision and sensitivity. Non-intrusive, EMI-resistant vibration sensing for critical infrastructure and harsh environments Optical fiber vibration sensors are transforming how industries monitor structural and mechanical systems in environments where traditional electronic sensors fall short. HAWK's Praetorian Fiber Optic Sensing System is the only system on the market that offers a single interrogator that.
