光纤光栅是九十年代初才迅速发展起来的一种光纤新技术,是光纤技术领域又一次重大突破,是光纤通讯发展史上及光纤传感技术中的一个重要里程碑,它将使目前已有的通信光缆的通信容量增加十几倍乃至几十倍;光纤光栅传感将传感器和信号传输集于一体,体积小,测量精度高,可靠性高,耐腐蚀,抗电磁干扰,抗雷
Fiber Bragg Grating (FBG) is a kind of optical fiber technology that developed rapidly in the early nineties. It is another major breakthrough in optical fiber technology. It is an important milestone in the history of optical fiber communication and optical fiber sensing technology. It will make existing The communication capacity of the communication optical cable has increased ten times or even tens of times; the optical fiber grating sensor has the advantages of small size, high measuring accuracy, high reliability, corrosion resistance, anti-electromagnetic interference and anti-thunder
