基于波分复用的光纤入侵探测系统
Fiber intrusion detection sensor based on WDM
摘要
提出在光纤入侵探测系统中应用波分复用(WDM)技术, 以进一步精简系统架构。该系统将不同干涉子系统通过不同波长加以区分, 并利用波分复用技术将不同波长的干涉子系统复用同一干涉模块。在信号接收端, 利用解复用的方式, 将各个不同波长干涉子系统信号分开, 从而获得不同干涉子系统中相对独立的时域信号。
Abstract
Fiber intrusion detection sensor based on wavelength division multiplexing (WDM) is proposed to simplify the architecture of the system. The system uses different wavelengths to distinguish the different interfering sub-systems. WDM technique is used to multiplex the different wavelength interfering sub-system by the same interfering unit. In the receiver of the system, the signal of different wavelength interfering sub-systems is divided by the demutliplexing. Thus, the independent signal of different interfering sub-systems is achieved.
