光纤传感器是利用光在光纤中传播引起光干涉、衍射、偏振、反射、损耗等物理特征的变化,进行各种物理测量的装置和系统。光纤传感器是光电传感器的一个分支,在需要探测某些微小部件或安装空间受到限制的情况下,不便于使用传统的光电传感器,于是光纤传感器应运而生。产品与技术发展现状光纤传感器一般由光源、接口、光导纤维、光电探测器、光调制机构和信号处理器等部分组成,来自光源的光通过接口进入光纤,光调制机构将光电探测器测量检测的参数调制成幅度、相位、色彩或偏振信息,最后利用微处理器进行信号处理。近年来,由于光纤传感器性能不断改进以及品种的不断增多,加之其拥有的 Optical fiber sensor is the use of light in the optical fiber propagation caused by light interference, diffraction, polarization, reflection, loss and other physical characteristics of changes in a variety of physical measurement devices and systems. Optical fiber sensor is a branch of the photoelectric sensor, in the need to detect some small parts or installation space is limited circumstances, not easy to use the traditional photoelectric sensor, so optical fiber sensor came into being. The status of products and technology The optical fiber sensor generally consists of light source, interface, optical fiber, photodetector, optical modulation mechanism and signal processor and other components, the light from the light source through the interface into the optical fiber, light modulation mechanism photodetector to measure the detection Parameter modulation amplitude, phase, color or polarization information, and finally the use of microprocessors for signal processing. In recent years, due to the continuous improvement of optical fiber sensor performance and the increasing variety, combined with its own
