摘　　要：经优化设计确定系统关键参数,研制了分布式光纤温度传感器。该系统以微机为核心,以普通通信光纤和包层涂锌光纤相结合作传感光纤,在国内首次实现上限为260℃测温,空间分辨率15.6m,温度分辨率7℃,测量距离1.5km,测量时间160s。A prototype of distributed optical fibre temperature sensor based-on a microcomputer, for the first time in China, has been developed and optimized by maximizing signal to noise ratio of the system. It has a spatial resolution of 15. 6m (limited by pulse width of laser), measuring time of 160 s,temperature resolution of 7C. sensing distance of 1. 5 km, and upper sensing limit of 260C.
