What is the function of a fiber optic sensor and how is it wired
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. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. Fibers have many uses in remote sensing. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Fiber optic sensors represent a cutting-edge technology used in a variety of industries to detect and measure changes in physical parameters such as temperature, pressure, vibration, and strain. This article will explore the principles behind fiber optic current sensors.

Angola Interferometric Fiber Optic Sensor
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. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
