Research Status and Development Prospect of Optical Fiber High-Temperature Sensors

Accurate temperature measurement needs in both research and industry have become more demanding and traditional temperature measurement technologies are struggling to keep up. Optical fiber thermometers have many unique advantages and are an option with much potential in the area of high temperature measurement. Research shows that fiber optic temperature sensors are capable of making accurate and precise measurements in a wide range of harsh conditions where other measurement technologies cannot and are a cost effective option in situations where traditional measurement technologies are currently used. Several typical high temperature fiber optic sensors are discussed in detail, focusing on the principle of operation, advantageous characteristics, and recent research developments, with the aim of aiding in further work with fiber optic thermometers.
