As a new application of laser technology in the field of opto-electronics technology, fiber-optic communications and optical fiber sensing technology have become the hotspot of engineering applications and research. In this dissertation, one fiber-optic fence alarm system has been designed, and some theorys of technology and algorithms of fiber-optic fence alarm system has been used. Then the feasibility analysis of the structure of the entire system and the program of experimental verification are made. And at last the experimental tests have been carried out. The dissertation can be divided into the follow aspects: In the aspect of technology and theory of the fiber-optic fence alarm system,Mach-Zehnder interference and reduce false rate of the system.Are used to improve the In the aspect of overall fiber-optic fence alarm system design, the basic design principles of system, system configuration, system architecture, positioning module,data analysis and so on,have been analysed in this dissertation. Then the experimental design and experimental validation program of the fiber-optic fence alarm system have been brought forward. In the
