ANALYSIS ON FOUR TERMINAL OPTICAL FIBER COMPENSATION NETWORK
四端光纤补偿网络的理论分析

Intensity disturbances are a key problem that hinders the advance and development of intensity modulation optical fiber sensors.results of researching show that the optical fiber compensation network is an effective method for restraining the intensity disturbances in the field of intensity modulation optical fiber sensors.By researching,the novel four terminal optical fiber compensation network were developed.In this paper,a comprehensive and systematic analysis for the principle and performances of the network has been made,which reveals the characteristics of the network and has important significance for the development and application of intensity modulation optical fiber sensors.Meanwhile,the network has reference value for intensity modulation optical measuring systems.
