Abstract

For traditional active temperature sensors, the accuracy is reduced under strong electromagnetic conditions, and in high voltage situations, there may be dangers such as electric sparks exploding. Therefore, a fluorescence lifetime optical fiber temperature sensor capable of operating in a series of complex environments such as strong electromagnetic, high voltage, and deep sea has been developed. This paper mainly introduces the system structure and data processing algorithm of the fluorescent fiber optic temperature sensor, and completes the experimental prototype. After preliminary calibration test, accurate measurement of 20-60°C has been achieved with an accuracy of ±0.6°C, and it has good stability and repeatability. It is well suited for use in the medical field, providing a reliable, low-cost solution for temperature sensing in the medical field.
