摘　　要：温度是表征物体状态的参数之一,在科学研究和工程应用中具有重要的理论意义和价值。在氧化、高温、腐蚀、电磁干扰等恶劣环境下,温度的准确测量一直是难题。传感器材料是进行温度测量的基础。蓝宝石单晶光纤具有物理化学性能稳定、熔点高、机械性能强等优点,是进行高温测试的一种首选材料。本文介绍了利用蓝宝石单晶光纤进行温度测量的几种方法,即蓝宝石光纤辐射高温测试技术、蓝宝石光纤光栅高温测试技术、蓝宝石光纤珐珀高温测试技术、蓝宝石超声波导高温测试技术的原理、现状、优缺点及发展趋势,并进行了比较,为蓝宝石光纤温度测量应用奠定基础。Temperature is one of the parameters that characterize the state of an object and has important theoretical significance and value in scientific research and engineering applications. Accurate measurement of temperature has been a problem in harsh environments such as oxidation,high temperature,corrosion,and electromagnetic interference. The sensor material is the basis for the temperature measurement. Sapphire monocrystalline fiber has the advantages of stable physical and chemical properties,high melting point and strong mechanical properties,and is a preferred material for high temperature testing. This paper introduces several methods for temperature measurement using sapphire monocrystalline fiber,namely sapphire fiber radiation,sapphire fiber grating,sapphire fiber optic and sapphire ultrasonic high temperature test technologies. The principles,current status,advantages and disadvantages,and development trends of these test technologies are introduced. The comparison will lay the foundation for sapphire fiber temperature measurement applications.
