摘　　要：利用光谱仪和PC搭建光纤法珀传感器解调系统简单、可靠,但存在体积大、测速慢等不足。为了解决这一问题,本文采用可调谐光纤法珀滤波器替代光谱仪,在DSP平台上进行了系统的搭建。在此基础上,进行了硬件和软件的设计,研制了一体化、便携式新型解调仪并进行了应变测量实验,实验结果证明了系统的可行性。Optical fiber Fabry-Perot sensor demodulation system set up with spectrometer and personal computer is simple and reliable, but has the disadvantages of large volume and slow test speed. To solve the problem, tunable optical fiber Fabry-Perot filter was adopted to replace the spectrometer, and the system was set up on DSP platform. The hardware and software of the system were designed and a novel integrated portable demodulation system was developed. Strain test experiment was carried out, and test result shows the feasibility of the system.
