Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required.

It is well-known the propagation of light in optical fiber is confined in the core of the fiber based on the total internal reflection (TIR) principle and near-zero propagation loss within the cladding, which is very important for the optical communication but limits its sensing applications due to the non-interaction of light with surroundings. Therefore, it is essential to exploit novel fiber-optic structures to disturb the light propagation, thereby enabling the interaction of the light with surroundings and constructing fiber-opti.

Fiber optic sensing technology uses the principle of light reflection to detect changes in the physical properties of the conveyor belt, such as strain, temperature, and vibration. If action is taken during this phase, then any fire suppression or cooling measures are much more likely to be effective. This article explores the different types of Fiber Optic Sensors, their working principles, and various applications. By improving the traditional Isolation Forest (IForest), a framework called Incremental Majority Voting Isolation Forest (IMV-IForest) is proposed. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of.
