Abstract

This paper aims to provide an overview of the dual Mach-Zehnder interferometric perimeter intrusion detection system (DMZIPIDS), propose a simulation model for the system, and give advice on the design of the system in accordance with simulation results. In this paper, the basic optical phase modulation mechanisms in optical fibers are described at first to clearly elaborate how the system works. Then, an introduction to the system, including its system structure, theory of operation, and noise sources as well as polarization-induced effects in the system, is described. A noise-involved and MATLAB-based simulation model of the system is proposed in order to predict the performance and study the characteristics of the system. Simulation results are presented and discussed.
