| Abstract: | 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. |
