一、概述自六十年代激光被发明以来,利用光的各种属性(干涉、衍射、偏振、反射、吸收、发光等)的光检测技术,作为非接触、高速度、高精确度的检测手段获得了飞速的发展。特别是由于低损耗光导纤维的问世以及检测用特殊光纤的开发,在光纤应用领域内继光纤通讯实用以后出现了一门崭新的应用光导纤维的检测技术——光纤传感技术。
I. Overview Since 1960s, when the laser was invented, the light detection technology using various properties of light (interference, diffraction, polarization, reflection, absorption, light emission, etc.) has been used as a non-contact, high speed and highly accurate detection means Get rapid development. In particular, due to the advent of low loss optical fibers and the development of special optical fibers for detection, a brand new optical fiber detection technology, optical fiber sensing technology, has emerged after the practical application of optical fiber communication in optical fiber applications.
