摘　　要：阐述了几种光纤温度传感器的概况和原理,重点介绍了双波长光纤温度传感器原理,并详细介绍了利用光纤测试温度的若干种方法.功能型光纤温度传感器是利用光纤的各种特性(相位、偏振、强度等)随温度变换的特点,进行温度测定.而传输型光纤温度传感器的光纤只是起到光信号传输的作用,以避开测温区域复杂的环境.最后通过对光纤温度传感器未来的发展趋势和特点,提出了一些看法.This paper introduces the general situation and theories about fiber-optic sensors, especially dual wavelength one. And some methods through it are showed in details. Functional fiber-optic sensors get the temperature by the nature of fiber-optic such as phase,polarization,intensity.But fiber-optic in transmitted ones plays the role of transmitting the optic sign in order to avoid the surroundings disturbance. In the end there are ideas about fiber-optic sensors' development trend and characteristics in the future.
