摘　　要：本文详细阐述了在特定条件下利用可调谐法布里-珀罗腔建立的F-P腔解调系统模型和通过检测F-P腔的相关参数而得到所测的参变量。在此基础上,笔者设计了采用 DSP 系统的光纤光栅传感器的解调器,其中 DSP 系统由 AT89C52 和 TMS320C5402 组成,其软硬件设计在文中均有着详细的阐述。The model of demodulation system based on Fabry-Perot cavity is described, and reference variables obtained by checking Fabry-Perot are presented. Based on this, the optical fiber Bragg grating demodulation system based on DSP system is designed, which is composed of AT89C52 andTMS320C5402. The design method of the demodulation system based DSP system is described, and the hardware and software designs are also given in the article.
