基于Mach-Zehnder干涉的全光纤防区型周界系统

All-fiber perimeter alarm system based on Mach-Zehnder interference

摘要: 为了对各种防区进行实时监测,准确分辨出入侵行为,提出了一种基于非平衡马赫-曾德尔结构干涉原理的全光纤防区型周界报警系统。对这种干涉结构进行了理论分析和实验验证,并在LabVIEW平台上开发了基于此传感结构的防区报警软件,在运行10d内,此系统准确报警率达95.1%。结果表明,此系统对突发事件有较好的模式识别能力,该结构在防区报警系统方面具有较好的效果。

Abstract: In older to monitor all kinds of regional perimeter and identify the intrusion accurately,an all-fiber regional perimeter alarm system was presented based on the non-equilibrium Mach-Zehnder interference.Theoretical analysis and experiments were carried out.The alarm software was developed on the labview platform.The alarm rate of the system reached 95.1% in ten days so that it could distinguish emergencies efficiently and could be used in perimeter alarm system.
