1概述20世纪90年代,发达国家已率先将光纤的传输与传感技术应用到周界防范入侵报警领域中,如英国、美国、以色列等。随着近十年来光纤技术的不断探索与研制,以光纤感知为探测手段的光纤探测报警系统已经逐步成熟与稳定,而光纤光栅周界报警系统以报警检测精度高、传感方式独特成为小范围高级别周界防范首选理 1 Overview In the 1990s, developed countries took the lead in applying optical fiber transmission and sensing technologies to the perimeter in areas such as the United Kingdom, the United States, and Israel. With the continuous exploration and development of optical fiber technology in recent ten years, the optical fiber detection and alarm system based on optical fiber sensing has gradually matured and stabilized. However, the optical fiber grating perimeter alarm system has the advantages of high alarm detection precision and unique sensing mode to a small area High-level perimeter prevention first choice
