Fiber Optics Sensors are devices that use optical fiber technology to detect and measure physical parameters in their surroundings. These sensors leverage the principles of light propagation through optical fibers to monitor various environmental factors. Fiber optics sensors offer advantages such as high sensitivity, immunity to electromagnetic interference, and the ability to cover long distances without signal degradation. Different types of fiber optics sensors exist, each tailored to measure specific physical quantities.
