摘要
提出了一种以ARM芯片S3C44B0X为核心,采用可调谐光纤F-P滤波器的光纤光栅解调方案。详细介绍了解调原理、系统的软硬件设计以及相关信号的数据处理。实验结果显示设计的系统灵敏度高、解调速度快、成本较低。
A fiber optic grating demodulation system based on the ARM chip S3C44B0X and adopting an optical fiber F-P tunable filter is designed. The demodulation principle, the hardware and software design, and the signal data processing are presented. The experiment results prove that this method has the advantages such as higher sensitivity, higher speed demod ulation and lower cost.
