消除光源波动等因素影响的光纤网络补偿技术

光纤网络补偿方法是提高强度调制光纤传感器精度行之有效的方法之一，它能消除因光源波动、耦合系数的变化、传输特性的变化以及光电器件漂移等因素的影响，文中介绍了常见的几种网络补偿方法的机理，最后介绍了我们近来的工作－数字式全光纤优化网络补偿技术的研究。

Compensation technology with optical fiber network for eliminating the effect caused by factors such as laser intensity fluctuation

Compensation technology with optical fiber network is one of the most effective ways to improve the accuracy of intensity modulation fiber-optic sensers. It can eliminate the effects caused by factors such as laser intensity fluctuation,variation of couple parameters ,variation of transmission characteristics and drifting errors in any opto-electronic element. This paper put forward the compensation theories of some kinds of common network and finally introduces our recent work-the research in compensation technology of digital all-fiber optimized network.
