Fiber-optic sensing system (brillouin)

Fiber-optic sensing system for distributed strain and temperature monitoring
Uninterrupted monitoring is essential to manage risks and maintenance of large structures. Where kilometers of concrete, steel or soil are to be monitored for the early signs of failure, distributed optical fiber sensors are a powerful and highly efficient tool.
With industry-leading accuracy, fibrisTerre’s unique digital BOFDA and BOFDR technology answers the demand for reliability in long-term monitoring of pipelines, power cables, railway lines and geotechnical infrastructure.

Key Features
 • Spatial resolution down to 20 cmDistance range up to 50 km fiber length
• Measurement repeatability: < 2 με for strain and < 0.1°C for temperature
• Full loop and single-ended measurement
• High-precision measurement of fiber length and attenuation
• Access to all raw data
• Field friendliness thanks to light weight and low power consumption

Typical Applications :

- Early failure detection in geotechnical structures
- Fatigue monitoring of bridges, tunnels, dams
- Oil and gas pipeline monitoring
- Strain and temperature monitoring in mining
- Displacement monitoring of river embankments
