摘要

The paper presents the spectral mode analysis of the proposed fiber-optic security system (FOSS) and achievements in processing the data from fiber-optic sensors, design and operating principles of the proposed system. The paper focuses on the cost reduction and simplification the FOSS design, while maintaining its high efficiency. The use of single-mode optical fiber of the G.652 type, allows increasing the protected perimeter length up to 40 km, providing the resistance to external influences. The proposed software is used to analyze changes in the light spot, recording mechanical effects in real time. The program supports several operating modes, including automatic adaptation to changing conditions, which minimizes the number of false positives. The FOSS demonstrates the high accuracy in laboratory conditions, which confirms its potential for use in the protection of extended objects.
