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. According to the National Fire Protection Association (NFPA) 70E: Standard for Electrical Safety in the Workplace, an arc-flash hazard is "a source of possible injury or damage to health associated with the release of energy caused by an electrical arc. An opto-electronic point sensor consists of a photodiode integrated in the head of the senso, which implements the opto-electrical conversion. This article explores the different types of Fiber Optic Sensors, their working principles, and various applications.
