Structural Health Monitoring

Structural health monitoring systems provide continuous or periodic data about the condition and performance of critical assets, including bridges, dams, tunnels, towers, pipelines, wind turbines, offshore structures and aircraft. By tracking changes in strain, temperature, vibration, acceleration and displacement, operators can identify developing problems, evaluate structural performance and make better-informed maintenance decisions.

Luna’s fiber optic structural health monitoring solutions combine rugged optical sensors, high-speed interrogators and data-acquisition software to monitor large structures over long periods of time. A single optical fiber can support hundreds or thousands of sensing points while remaining immune to electromagnetic interference and resistant to corrosion, making fiber optic sensing well suited for demanding civil, geotechnical and energy applications.

What Can Fiber Optic Structural Health Monitoring Measure?

Luna structural health monitoring systems can be configured to collect both static and dynamic measurements from critical components and structures. Depending on the application, monitored conditions may include:

• Structural strain and long-gage deformation
• Temperature and thermal changes
• Vibration and acceleration
• Displacement and movement
• Fatigue, bending and dynamic loading
• Changes associated with damage, wear or delamination

Luna supports structural health monitoring applications with HYPERION multipoint fiber optic sensing systems, fiber Bragg grating sensors and high-definition distributed fiber optic sensing technologies.
