This is a companion discussion topic for the original entry at https://www.ofscn.net/fbg-products/angle
Welcome to the OFSCN® official forum. This topic discusses the technical implementation of bending and angle monitoring using Fiber Bragg Grating (FBG) technology.
Technical Principles of FBG Angle & Curvature Sensing
The OFSCN® Fiber Bragg Grating Angle/Curvature Sensor is designed to monitor two-dimensional angle changes and structural bending. Unlike traditional mechanical or electronic inclinometers, these sensors leverage the wavelength shift of FBGs induced by structural deformation.
When the sensor body undergoes bending, the strain distribution across the internal fiber cores changes. By measuring these specific strain differentials, the system can precisely calculate the curvature radius and the resulting angle of deflection.
Key Applications
- Structural Health Monitoring: Monitoring the bending of bridges, tunnels, and large-scale beams.
- Shape Sensing: Tracking the real-time geometric deformation of flexible structures.
- Geotechnical Engineering: Measuring displacement and tilt in soil or rock masses.
