一、光纤传感器概况光学纤维是六十年代发展起来的新的光学材料。拉制成直径为5～10μm丝状物的光学材料称为光学纤维。利用光在均匀、透明玻璃柱的光滑内壁上的接连不断的反射,它可以将光从一端传送到另一端。主要用于光能和图象的传递。开始,光纤主要用于通讯,随着光纤通讯的发展,出现了低损耗,宽频带光纤,这样光纤的应用也就更加广泛了。人们发现一些光纤对环境敏感特性虽然不利于通讯,但可用于测量某一些“量”的变化。
First, the optical fiber sensor Overview Optical fiber is the development of the sixties new optical materials. Optical materials drawn into filaments having a diameter of 5 to 10 μm are called optical fibers. Using the continuous reflection of light on the smooth, smooth, inner walls of a uniform, clear glass column, it transmits light from one end to the other. Mainly used for the transmission of light energy and image. At the beginning, optical fiber was mainly used for communication. With the development of optical fiber communication, low-loss and broadband optical fibers appeared, so the application of optical fiber was more extensive. Some people find that some of the optical fiber of the environment-sensitive properties, although not conducive to communication, but can be used to measure some “quantity” changes.
