Abstract

Optical fiber mesh can be applied on some fences to secure some protective facilities. It is necessary to give the fiber macro bending signal in order to detect an intruder at the initial intrusion stage with the off signal from fiber cutting. Therefore, in this work, we made two step signal processing algorithm of the optical fiber mesh for detecting the intruder effectively. First step is composed of the discrimination processing whether the fiber has some macro bending or not. If the signal tells the macro bending, then it means that some intruder tries to invade. Second step is the signal destruction by cutting the optical fiber. This step means that the intruder invaded by cutting the optical fiber mesh.
