The distributed fiber acoustic/vibration sensing instrument, including software, is a high-performance system based on Rayleigh scattering and optical time-domain reflectometry, integrating optics, communications, microwaves and intelligent algorithms. Every point along the sensing fiber acts as an independent sensor to measure and monitor time-varying acoustic/vibration signals, with high sensitivity, fidelity and frequency response. Fiber sensing offers electromagnetic immunity, passive explosion protection and intrinsic safety, with easy maintenance and long life in many extremely harsh environments. The highly integrated, compact distributed sensor covers long measurement paths. The system also provides interactivity, security, stability and confidentiality with excellent overall performance.
