摘　　要：本设计基于LabVIEW可视化界面技术和光纤Bragg光栅波长解调的原理,对微型光谱解调分析模块的数据采集系统进行深入研究。并介绍在LabVIEW平台下进行串行通信采集FBG传感温度信号和数据处理的技术,形成基于LabVIEW友好界面、功能完备的光纤光栅解调系统,取得较好的试验效果。同时解决普通光谱解调设备成本高、体积庞大和只简单显示波长的难题。This design is based on LabVIEW interface and Fiber Bragg Grating technology in principle of the wavelength demodulation. It carried on a thorough research to the the data collects system according to the miniature spectrum solution adjusts analysis instrument mold piece and introduced the platform in the LabVIEW serial communication under the FBG sensor temperature signal acquisition and data processing technology and formed a full-featured fiber grating demodulation system based on the LabVIEW friendship interface and it made a good test results. At the same time, it solves the problem of the general high cost of spectrum demodulation equipment, size and only show the wavelength of the problem easy.
