摘　　要：介绍了光纤光栅传感器的解调原理,设计并实现了一个基于可调谐F-P滤波器的光纤光栅波长解调系统。利用数据采集卡采集光纤光栅的光谱数据上传给计算机,用LabVIEW编写了对数据进行实时处理的软件。实验结果表明该系统有效可行,可以获得±0.3℃的测量精度,并具有对50个以上的光纤光栅传感器进行解调的潜力。This paper introduces the demodulation principle of FBG sensor, designs and realizes a wavelength demodulation system for fiber Bragg grating based on tamable F-P filter. Data Acquisition Card is utilized to gather the spectrum data of fiber Bragg grating to upload to the computer, and LabVIEW is used to compile a real-time data processing software. The experiment result shows that this system is effective and feasible, can reach a measurement accuracy of ±0.3℃, and has a potential of making a demodulation on above 50 fiber Bragg grating sensors.
