DAS system is a micro-structured optical time-domain reflectometry sensing technology based on optical coherence detection, which can continuously record the acoustic signal transmission and spatial distribution of sound field along the long distance optical fiber. The minimum detectable strain of the system can be up to yarna strain, and the response frequency band covers the infrasound frequency band to the ultrasonic frequency band. The system can be applied to the distributed measurement of seismic wave, micro-vibration and micro-strain, etc., and has great application potential in the fields of resource exploration, seismic monitoring, pipeline safety, perimeter safety and the health of major engineering structures. Enhanced optical fiber with scattering can achieve higher sensitivity, signal-to-noise ratio and sensing distance.
