摘　　要：光纤光栅传感器作为光纤无源器件,因具有感测和传输双重功能而受到广泛关注,其核心技术之一是波长解调。研究并实现了一套基于ARM与C#.Net的光纤光栅数据解调系统,系统分为硬件和软件两大部分。硬件系统包括宽带光源、光路系统和电路系统三部分,通过ARM控制整个硬件系统进行波长解调、数据传输。软件系统是基于C#开发的C/S架构的上位机软件,人机交互方便,波长解调准确,可将得到的波长数据解析为实际物理量,并将相关数据存入数据库。Fiber Bragg grating（ FBG） sensor which is a passive fiber parts, has been widely concerned because it has the dual func-tions ： the sensing measures of the data and the network transmission function. The key technology of FBG sensor is wavelength de-modulation in this paper, a set of FBG wavelength demodulation system has been designed and realized based on ARM and C#.Net. The system design includes hardware and software. Hardware system includes broadband light source, optical path system and circuit system. ARM is used to control hardware system for wavelength demodulation and data transmission. Software system is im-plemented based on C / S structure, which is very convenient for the communication between user and computer and can demodulate the wavelength exactly. At the same time, the software system can parse the wavelength as the actual physical quantities and store relevant data in the database.
