The methods of demodulation and multiplex technique used in fiber grating sensor are introduced in this dissertation 并详细介绍了光纤光栅传感中的解调技术以及复用技术。
Therefore, lots of researchers are interested in fiber grating sensing multiplex techniques 因此,光纤光栅传感器的复用技术引起了世界各国有关研究者的广泛关注和极大的兴趣。
The fundamental theory of fiber grating is also demonstrated . the basic principle of fiber bragg grating sensor and demodulation and multiplex technique can be found in this dissertation 分析了以光纤光栅传感作为基本传感器件的传感器的基本原理以及光纤光栅传感解调和复用技术的原理及应用。
Therefore, the smart fbg sensors multiplexing system is more rational and smarter than the conventional counterpart . 3 . a novel multiplexing system which combined with ingaas array and f-p filter is raised, analyze the disadvantage of the fbg multiplex technique which combined 5.提出了具有远程监控功能的光纤光栅传感复用系统,该系统不仅可以通过光纤光栅感测被测量变化,而且可以根据感测到的传感信息通过光纤控制通
Sensors using fbg as the sensing component have many advantages including light weight, small size, anti electromagnetism interference, convenience in fiber connecting, wavelength absolute coding etc . multiple point detection of materials ( temperature, strain etc . ) can also be achieved by connecting several sensors into a net using variety of multiplex techniques and embedding it into or sticking on the surface of the material or structure 以光纤布拉格光栅(fbg)为传感元件的传感器具有重量轻、体积小、抗电磁干扰、易于光纤连接、波长绝对编码等优点,还能把多个传感器利用各种复用技术连接成传感网络,埋入材料和结构内部或贴装在其表面,实现对其特性(如温度、应变等)的多点监测。
