具有低损耗、宽带、无感应等多种优良特性的光纤正在公共通信和工厂、大型建筑和电力设施等的通信控制电路等广泛的领域中获得应用。光纤在检测技术方面也有很宽的应用范围,例如,利用其低损耗、无感应性进行检测数据传送和以前的光检测,利用光纤的细线径、柔软性、电绝缘性等特长的检测,以及用光纤做传感器的检测等。本文介绍这些光纤检测技术的一个侧面。 Optical fibers with many excellent characteristics of low loss, broadband, non-sensing and the like are used in a wide range of fields such as public communication and communication control circuits in factories, large buildings and power facilities. Optical fiber also has a wide range of applications in the detection technology, for example, the use of its low loss, non-responsive detection of data transmission and the previous light detection, the use of optical fiber fineness, flexibility, electrical insulation and other specialty detection, As well as the use of optical fiber sensor testing. This article describes one side of these fiber optic detection technologies.
