How FBG Sensors Are Changing the Way We Measure Things
Imagine a fiber optic cable that can precisely sense strain and temperature along its entire length. That's the appeal of Fiber Bragg Grating (FBG) Sensors . These sensors are written in the core of the optical fiber enabling it to create periodic structures which can reflect specific wavelengths of light. The strains and temperatures experienced by the fiber cause the shifting of the wavelengths that are reflected. This results in usable and accurate measurements. Uses of FBG Sensors Optical fiber sensors provide distributed sensing in real time. Here's how they are helping to change industries. Structural Health Monitoring (SHM) - The civil engineering industry installs Bragg grating sensors embedded in structural components to measure distributed stresses occurring in elements of bridges and tunnels. Aerospace and Defence - The aerospace industry employs optical fiber sensors to measure strain on components during ground and flight tests for assessment, to assess perfor...
