π General Description Fiber sensing refers to the use of optical fibers as sensors to detect changes in temperature, pressure, strain, vibration, chemical composition, or electric/magnetic fields . These sensors leverage changes in light propagation within the fiber to sense and measure environmental or structural conditions in real-time. π§ Technical Description Fiber optic sensors work by transmitting light through a glass or plastic fiber and analyzing how the light is altered due to external perturbations. These changes may affect intensity, phase, polarization, wavelength, or transit time of the light, depending on the sensing mechanism (e.g., Bragg grating, interferometric, or distributed sensing techniques). π️ Applications Description Fiber sensors are widely used in: Structural Health Monitoring (bridges, tunnels, dams, buildings) Energy Sector (pipeline leakage detection, geothermal sensing, wind turbine monitoring) Aerospace and Defense (vibrati...
