Investigation on the Novel Accelerometer based on the Fiber Gratings

Abstract

随着光纤通信技术和光纤传感技术的迅猛发展,许多新兴技术被应用于传统工业当中。近年来,基于光纤技术的加速度传感器研究越来越受到专家学者的重视。与传统加速度计相比,光纤加速度传感器具有其独特的优点,主要包括:抗电磁干扰、体积小,质量轻、动态范围大、高灵敏度和分辨率、易于植入材料内部,易于形成传感网络和远距离传输。目前在已报道的文献中,光纤加速度传感器主要有以下几种类型:强度调制型、相位调制型、波长调制型、偏振调制型。本文的主要工作是对D型光纤Bragg光栅(D-FBG)和长周期光纤光栅(LPFG)的弯曲特性进行研究,在此基础上完成基于光纤光栅加速度传感器研究的实验与分析。D型光纤由于其结构的非圆对...With the rapid development of fiber communication technology and sensing technology, lots of new technology has been applied to the traditional industries. In recent years, accelerometers based on optical fiber attract many interests. Optical acceleration sensors have many advantages over conventional ones, such as immunity to electromagnetic interference, small size, light weight, large dynamic r...学位:理学硕士院系专业:信息科学与技术学院电子工程系_无线电物理学号:2312006115249
