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. This article explores the different types of Fiber Optic Sensors, their working principles, and various applications.

We demonstrate the fabrication of fiber-optic Fabry-Perot interferometer (FPI) temperature sensors by bonding a small silicon diaphragm to the tip of an optical fiber using low melting point glass powders heated by a 980 nm laser on an aerogel substrate. Besides, they exhibit high measurement speeds and high sensitivity due to the large thermal diffusivity and the large thermo-optic coefficient of silicon and the small size of the sensing element. Fiber Bragg gratings are very efficient at temperature sensing and are easy to implement; however, they always need additional techniques to discriminate the Bragg shifts by temperature and by strain/compression and they also require expensive phase-masks.

Path: 500 meters, mixed indoor/outdoor with light conduit, 2 splices, standard connectors. Fiber-optic cable materials typically cost $1 to $6 per linear foot, depending on fiber count and cable type. Commercial building installations with 100-200 network drops generally range from $15,000 to $30,000. Single-mode fiber costs less per foot than multimode fiber, but it requires more.
