Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Jose Miguel Lopez-Higuera: Handbook of Optical Fiber Sensing Technology, John Wiley & Sons, 2002. Fibers have many uses in remote sensing. Depending on the. Fiber optic sensors are used in a wide range of fields, including: Structural Health Monitoring: Real-time monitoring of the physical condition of structures. These sensors mainly measure physical quantities, such as object displacement and pressure, by. birth of fiber optic sensors.
