摘　　要：提出了一种新颖的三节点式全光纤传感补偿网络，设计了当节点支参数受环境温度、振动等影响时的最优化网络结构。通过对这种网络节点作了温度和振动实验，应用现代信息论分析计算了传感补偿网络的信息熵。实验研究表明，这种网络信噪比大，是一种先进光纤补偿网络。A novel three-point all optic fiber compensation network is put forward,and an optimal network is designed for adapting the nodes influenced by environmental temperature and vibration etc.On the basis of temperature and vibration experiments being carried out for the nodes,the information extropy of the sensing and compensation network is analysed and computed by the modern information theory.The experimental research shows that this network has a large signal and noise ratio and is an advanced optic fiber compensation network.
