Abstract

Background Since the phase-sensitive optical time-domain reflectometry (Ф-OTDR) concept was proposed in 19931, ФOTDR has undergone rapid development and extensive studies. The first practical DVS system based on Ф-OTDR was demonstrated with a powerful narrow linewidth laser in 20082. Ф-OTDR is capable of covering long measurement range while maintaining high sensitivity and spatial resolution along the sensing fiber3,4. Based on this, researchers have made great effort on Ф-OTDR sensing performance improvement, including sensing distance, sensitivity, spatial resolution, frequency response range, event recognition accuracy, etc. Based on its superior long-distance and high-resolution distributed vibration/acoustic sensing capabilities, Ф-OTDR technology has been widely used in earthquake monitoring, oil and gas resource exploration, pipeline leak detection, perimeter intrusion monitoring, cable partial discharge detection and other fields with a large number of successful application demonstrations. In the recent work5 entitled "Advances in phase-sensitive optical time-domain reflectometry" published in Opto-Electronic Advances, DOI: 10.29026/oea.2022. 200078, Prof. Liyang Shao et al. present in detail the research progress and applications of DVS/DAS technology based Φ-OTDR. This article was selected as the back cover paper of Volume 3, Issue 5 of OEA in 2022, and was recently selected as a highly cited paper by Web of Science.

光纤分布式振动/声学传感的基石:Ф-OTDR

自相敏光学时域反射计(Ф-OTDR)概念于19931年提出以来，ФOTDR得到了迅速的发展和广泛的研究。第一个实用的基于Ф-OTDR的分布式交换机系统在2008年用一个强大的窄线宽激光器进行了演示。Ф-OTDR能够覆盖较长的测量范围，同时保持沿传感光纤3,4的高灵敏度和空间分辨率。基于此，研究者在Ф-OTDR传感性能提升方面做了大量工作，包括传感距离、灵敏度、空间分辨率、频响范围、事件识别精度等。Ф-OTDR技术基于其优越的远距离、高分辨率分布式振动/声传感能力，已广泛应用于地震监测、油气资源勘探、管道泄漏检测、周界侵入监测、电缆局部放电检测等领域，并取得了大量成功的应用示范。在最近发表在《光电进展》杂志上的题为“相敏光学时域反射法的进展”的工作中，DOI: 10.29026/oea.2022。20078，邵立阳教授等详细介绍了基于Φ-OTDR的DVS/DAS技术的研究进展及应用。这篇文章被选为OEA 2022年第5期第3卷封底论文，最近被Web of Science选为高被引论文。
