Abstract

Abstract: A new temperature extrapolation method, which is used to broaden the measurement range of a sapphire optical fiber blackbody cavity temperature sensor, is proposed. A transient heating black body cavity extrapolation model is set up by analyzing the thermal conductivity law of the blackbody cavity, and the method of separation of variables is used to solve the extrapolation model. The sensor can be used to measure the transient high surface temperature (3 005 ℃) by temperature extrapolation. Experimental verification of the extrapolation method is designed and completed. When a high power and high frequency modulated CO² laser pulse is used as exciting source to heat the sensor to 1 500℃, the measured time response of the sensor is on the order of 10_-2 s. The sensor and a high-speed infrared thermometer are simultaneously used to measure the variations in temperature of the coatings inside and outside the blackbody cavity by using CO² laser step pulse. The result shows that the extrapolation model is valid.

Key words: technology of instrument and meter, extrapolation, blackbody cavity, transient ultra-high temperature, sapphire optical fiber temperature sensor
