摘要
对比总结了基于拉曼散射、布里渊散射与瑞利散射的三种主要DOFS技术的原理及特点,介绍了DOFS系统在输电线路舞动及雷击监测领域的国内外研究及应用现状;对基于分布式光纤传感的架空输电线路舞动、雷击监测技术目前存在的不足进行了分析;指出分布式放大、光脉冲编码、多参量融合以及通感一体等关键技术将是该领域下一阶段的发展趋势与研究热点。
The principles and characteristics of the three main DOFS technologies based on Ra-man scattering,Brillouin scattering and Rayleigh scattering were compared and summarized,and the research and application status of DOFS systems in the fields of transmission line dancing and light-ning strike monitoring at home and abroad were introduced.The shortcomings of overhead transmis-sion line dancing and lightning monitoring technology based on distributed optical fiber sensing were analyzed.It was pointed out that key technologies such as distributed amplification,optical pulse cod-ing,multi-parameter fusion and synesthesia integration would be the next stage of development trend and research hotspot in this field.
