Paper Abstract

The measurement theory of optical fiber F-P temperature sensor is analyzed according to difficult problem that temperature is real-time measured in the study of thermal interaction between laser and bio-tissue. The model of temperature and strain is established. The work point stabilization method of optical fiber F-P sensor is studied. The optimal model of low fineness optical fiber F-P sensing system is established based on the technique of dual optical wavelength stabilization. The experimental device of real-time measurement temperature is build. The experimental results show that the sensor has higher measurement precision and small bulk. And the hurt is little for bio-tissue. It can be used to the real-time temperature measurement of bio-tissue efficiency. When the sensor is used to the continuum temperature measurement, the maximum absoluteness error is 0.63°C and the maximum relatively error is 1.4%. When the sensor worked half hour, the maximum cumulate error is 1.3%.
