The fiber optic sensor has an optical fiber connected to a light source to allow for detection in tight spaces or where a small profile is beneficial. Jose Miguel Lopez-Higuera: Handbook of Optical Fiber Sensing Technology, John Wiley & Sons, 2002. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of. This article explores the different types of Fiber Optic Sensors, their working principles, and various applications. Driven by the monumental data deluge from genome sequencing projects, scientists have developed these ultra-sensitive platforms capable of monitoring everything from cancer biomarkers to viral pathogens in real-time 1 3. Phase change of a light wave through an optical fiber of original length L that has been stretched by a length ? There is a trade-off between distance range and frequency bandwidth (due to time-of-flight limitations).
