Abstract

In order to enhance the security of underground cultural relics protection

this paper presents an optical fiber sensing equipment for perimeter security.The equipment is principally based on optical fiber Mach-Zehnder interferometer and applied to the underground motion wave detection perimeter security.Through the study of the interference waveform

it offers sufficient information for detection

The amplitude frequency characteristics of the vibration signal can be recovered from other interference waveform.Through the application

some key features are achieved:the equipment can detect the mining region within a radius of 25 meters;the equipment can support 64probes;and the equipment can identify the warning time within2 seconds.
