摘要
阐述了光纤温度测试系统的感温机理，及其监视光源的参考通道、单端式结构探头和为克服环境温度变化对光源及探测器造成影响而设置的恒温装置。文中还介绍了为适应探测器检测到的微弱信号而设计的信号放大及检测系统。经安装调试和实验证明，本系统性能稳定，精度良好，探头尺寸小，适用于铁道机车车辆的温度测试和控制。
Expounds the temperature semsitive principle of the optical fiber devices of the tempera-ture testing system,and the referenee channels of the surveillance light source,and the single termi-nal style ofthe structural probe。and the temperature stabilization devices used to overcome the ef-fects of the environmental temperature on the light sources and the detectors.In addition,introducesthe singnal amplifying and measuring system used to measure the microsingnal by using of thedetectors。
