Fiber optic temperature sensors operate based on changes in light properties as it travels through the fiber. In addition, they are easily available, with a large variety of off-the-shelf sensor configurations. So for which applications does it make sense to stick with a tried-and-true solution? Where might a process need a more innovative solution when it comes to thermal sensing? To answer those. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic interference, remote detection, multiplexing, and distributed measurement advantages. This paper reviews the sensing principle, structural design, and. Jose Miguel Lopez-Higuera: Handbook of Optical Fiber Sensing Technology, John Wiley & Sons, 2002.
