YOSC-DAS-M distributed optical Fibre acoustic wave monitoring system is a highly reliable, industrial-grade optical fibre vibration sensing product developed by YOSC for industrial applications.
DAS fibre distributed acoustic monitoring system uses the spatial interference phenomenon of backscattered Rayleigh light, and realizes real-time demodulation of frequency, phase, amplitude and position of fast variable acoustic waves through high-speed signal acquisition and data processing technology. It can be widely used in distributed measurement of seismic wave and micro-vibration.
