摘要
利用3×3耦合器解调算法实现对光纤沿线破坏行为的探测及预警.在确定破坏行为发生的基础上,通过将光源切换为窄带光源,使Mach-Zehnder干涉系统工作.利用互相关方法实现对破坏行为的精确定位.详细介绍并分析了该方法的系统光路和探测定位原理.
Abstract
A 3 × 3 coupler demodulation algorithm was used to detect destruction along the fiber.Based on confirming the occurring of the destruction,by switching the broadband to narrowband source,Mach-Zehnder interference system works.The cross-correlation method was used to realize precise positioning,thus achieving the goal that defenders are led to stop acts of sabotage to prevent the occurrence of malice.The optical path was presented,and the detecting and locating principle was analyzed in detail.
