摘　　要：针对目前市场上的光纤光栅解调仪体积大、功耗高的缺点,提出了将DSP应用于光纤光栅解调系统实现波长解调的方案;同时,为了减小DSP运算的数据量,提高光纤光栅解调系统的实时性,提出了一种光谱寻峰算法,通过与Mat l ab中的峰值检测模块的处理结果进行对比分析,证明了算法的有效性。In view of present fiber grating demodulation devices having large volume,and high power consumption on the market,one point that use DSP to realizes wavelength demodulation for the fiber grating system is put forward;what＇s more,in order to reduce the operation data quantity on DSP and improve the real-time of fiber grating demodulation system,a kind of spectral peak detect algorithm is also put forward,comparing with the Matlab peak detection module test result,it＇s validity has been proved.
