提高BOTDR传感系统性能的方法研究
Research on the method for improving the performance of BOTDR sensing system
摘要
Abstract
In order to improve the sensing performance of Brillouin optical time domain reflectometry (BOT-DR) technique,this paper analyzes the mutual restriction between the spatial resolution and the frequency measurement accuracy,then introduces three kinds of techniques and the methods proposed in recent years to solve the problem:the pulsed pre-pump technique,double pulse detection technique and pulse coding technique.The paper describes the basic principle and advantages of the three techniques,and analyzes the experimental results of the sensing system.关键词
