HZ-iDAS Distributed Acoustic Sensing System
Transform your fiber optic cable into thousands of vibration sensors. Achieve real-time, long-range monitoring with high-precision coherent Rayleigh scattering technology and AI pattern recognition.
How iDAS Works
Based on OTDR and coherent Rayleigh scattering, the system detects micro-vibrations along the fiber caused by acoustic waves.
High Sensitivity Laser
Uses a narrow-linewidth single-frequency laser to inject pulses into the fiber. Any external vibration changes the phase of the backscattered light.
AI-Driven Analysis Platform
Real-time Phase Display
Visualizes vibration signal phase curves and demodulation signals for every point along the fiber in real-time.
Audio Reconstruction
Select any point on the cable to "listen" to the environment. The system restores the sound signal in the time domain.
Spectrum Analysis
Performs frequency analysis to identify signal types and background noise characteristics.
AI Pattern Recognition
Intelligent algorithms automatically classify intrusion events.
