Research on Optical Fiber Temperature Sensor and Compensation Method

This paper explained the utilization of the properties of optical fiber sensor such as high insulation, anti electromagnetic fields, convenient installation small size. These properties make it possible for measurement of temperature of equipments under high voltage, high magnetic fields. With the two wavelength light sources and the feedback optical fiber path, the accuracy of measurements is significantly increased. The theory and repeated experiments results shows that the proposed methodology discussed in this paper can measure temperatures with high accuracy. The system is simple and reliable, the cost is low and the installation is convenient and other advantages.
