By harnessing the power of fiber optic sensors, we can ensure the integrity of our infrastructure, safeguard communities, and build a more resilient future.
What are Fiber Optic Sensors?
Fiber optic sensors use optical fiber to detect changes in physical quantities, such as temperature, pressure, strain, vibrations, rotations, and chemical species concentrations. Fiber sensors can be used in tight spaces or where a small profile is beneficial.
Real-World Applications of Fiber Optic Sensors
Fiber Optic Sensor technology has proven versatile and effective in various real-world applications.
From monitoring the structural integrity of critical infrastructure to detecting potential hazards in harsh environments, fiber optic sensors have demonstrated their value in enhancing safety, reducing costs, and improving efficiency.
For instance, Sensuron’s Maximum Precision DFOS Systems, such as the RTS250+ DFOS System, offer high-speed and high-resolution monitoring capabilities, making them ideal for applications that require real-time data and precise spatial resolution.

Fiber Optic Sensing Monitoring Bridges
Fiber optic sensors embedded in bridges can monitor strain, load, and structural integrity in real time, providing critical insights into the bridge’s condition.
This technology is particularly valuable for long-span bridges, suspension bridges, and bridges in harsh environments where traditional monitoring methods may be inadequate.
The Oresund Bridge, which connects Denmark and Sweden, is a prime example of the effectiveness of FOS in bridge monitoring. This 16-kilometer-long bridge is a critical transportation link between the two countries, and its safe operation is paramount.
By utilizing FOS, engineers can monitor stress and temperature changes in real time, enabling them to:
- Detect potential issues before they become major problems.
- Optimize maintenance schedules and reduce downtime.
- Extend the lifespan of the bridge.
