Classification of Fiber Optic Sensing by Principle

This article explores the different types of Fiber Optic Sensors, their working principles, and various applications. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Due to its small size, low cost and ease of fabrication leading it to replace traditional sensors which were used frequently before th birth of fiber optic sensors. For these applications fibers are made more susceptible and sensitive to the same external mechanisms against. Fiber optic sensors are sophisticated devices that utilize light transmitted through optical fibers to detect and measure various physical, chemical, and environmental parameters.
