摘　　要：研究了基于合成光学相干函数的长距离分布式光纤传感系统,阐述了系统工作原理,测量了10.225km光纤末端6个连续反射点,空间分辨率达到了2.20m,并验证了反射光解调信号强度与回波损耗的对应关系。We research into a distributed fiber-optic sensor system for long distance measurement based on synthesis of optical coherence function. The operation principle of the system is analyzed and verified by the experiments, in which six reflection points at 10.225km are located precisely with a spatial resolution of 2.20m. Then we verify the power of demodulated signal is related to the return loss.

关 键 词：光学相干函数 分布式传感 回波损耗 空间分辨率
