摘要:By sputtering and plasma spraying technology, a sapphire optical fiber blackbody cavity temperature sensor of tantalum (melting point is 2997 ℃ ) - zirconium oxide (melting point is 2715 ℃ ) thin film was developed. Static calibration system for the sensor to measure target temperature 1721 ℃ is also designed by using three oxygen (produced by water electrolysis) flame guns. When its impact resistant capacity is more than 50MPa, the corresponding temperature is 2802 ℃ . A high power and high frequency modulation CO 2 laser pulse is used as exciting source to heat it to 1500 ℃ , and the dynamic calibration device is designed independently, thus this sensor in experimental results show a time response on the order of μs. Signal collection and transmission through fiber optic cable are proposed, which can meet the need of transient high temperature measurement in harsh environment.
