OPM在光纤传感中的应用
Applications of OPM in fiber sensing
摘要
光纤传感随着光通信技术的成熟而得到快速发展,成为传感领域的主要方向之一,其中利用光纤布拉格光栅(FBG)的波长漂移检测环境变量的技术日趋完善。而对波长的检测,采用光性能监测模块(OPM)是一种行之有效的手段。OPM具有对光波长及波长漂移监测精确、体积小和可靠性高等特点。文章作者系统地阐述了FBG的工作原理和OPM的技术特点,并将两者组合搭建成传感测试平台。
Abstract
The Optical Fiber Sensing (OFS) technology has been rapidly developing with the evolution of the optical communication technologies and has become one of the main research subjects in the sensing area, in which the environmental monitoring technology using the wavelength shift of FBG is being perfected. As an effective technique for wavelength testing and characteristic of compact package and high reliability, Optical Performance Monitoring (OPM) module can be used to perform accurate monitoring of wavelength shift. In this article, the working principle of FBG and the technical features of OPM are systematically stated and a sensor testing platform is set up on the basis of combining them.
