| 摘 要： | 由于散射光的相位变化对外部扰动极其敏感,相位敏感光时域反射(Φ-OTDR)技术具有高响应速度、超高灵敏等特点。相比现有的其他分布式光纤传感技术,Φ-OTDR技术在环境适应性与光缆布设的便捷性方面有明显的优势。本文介绍Φ-OTDR系统的原理、结构、性能及应用情况,并对其发展趋势进行展望。

| Abstract: | Since the phase change of the scattered light is extremely sensitive to external disturbances, the phase sensitive optical time-domain reflectometer(Φ-OTDR) technology has the characteristics of high response speed and ultra-high sensitivity. Compared with other existing distributed optical fiber sensing technologies, Φ-OTDR technology has obvious advantages in environmental adaptability and convenience of optical cable layout. This article introduces the principle, structure, performance, and application of the Φ-OTDR system, and looks forward to its development trend. |
