摘要：
This design of the demodulation system of the wavelength information of the FBG; strain sensor was based on data acquisition system of DSP and FPGA, which can realize real-time detection and analysis of the multi-point strain. FBG strain sensor is an optical passive instrument. Through the demodulation analysis of the wavelength drift, the variation of corresponding strain can be calculated. This design includes: the demodulation principle of FBG strain sensor, the components of demodulation system, hardware design and analysis of experimental data.
