摘要
光纤光栅传感技术是国际上近十年发展起来的新型传感技术,既用光纤感测信号又用光纤传输信号,是以光纤为载体的传感技术的最杰出代表。目前该技术已经相对成熟,并成功地应用于多个相关行业。介绍了在光纤光栅技术平台上研制出的传感器的特点、工作原理及其在水利监测中的应用,着重于光纤光栅传感技术在水位遥测及大坝安全监测上的应用。
As a new technology emerged worldwide during the last decade, fiber optical grating sensors have ranked first among all optical fiber ones. Adopting optical fiber to measure and transmit signals, this technology has been developed well, and applied successfully in several industries concerned. In this article, the author introduces its features, operation principles, and application in hydrological monitoring, focusing on its advantages in water level telemetry and dam safety monitoring.
