摘要
本文介绍一种新颖的三节点式光纤强度调制传感器全光纤补偿网络的原理和建模。研究表明,这种网络可补偿光源波动、传输损耗变化、光电器件特性漂移等影响。我们又进一步研究了由于网络节点特性变化所引入的误差对检测精度影响,讨论了在一定检测精度要求下,这种光纤补偿网络的优化设计。
This paper describes a novel all fiber compensation network for an intensity modulated optic fiber with three-access and its mathmatical model. It can be seen from the study that the compensation network can resist the flectuation of optical source,the variation of fiber transmission losses ,and the drift of opto -electrical receiver and amplifier. We have also discussed the influence of the variation of the characteristic parameter on the measurement error and shown a design of the network.
