Some issues of developing fiber-optic systems for protection of distributed parameters

Abstract

This article deals with the problem of ensuring protection of limited access objects and other objects of state significance from unauthorized access. There is given the analysis of systems already developed by Russian and foreign scientists. A passive perimeter security system is proposed for consideration the main element of which is an optical fiber. The measurement principle is based on controlling the magnitude of the additional dissipation losses under mechanical action measured in dB. There have been carried out field experiments using the proposed security system. In conclusion there are describes the results of the study using a reflectometer.
