摘　　要：采用自主研发的可调谐窄带光源和光波分复用联合空分复用技术研究并实现了新型大容量光纤光栅传感解调系统。实验结果表明,系统可实现32通道超过600个监测点的实时并行监测,有效提高了传感解调系统的系统容量和信噪比,可满足大型工程对光纤光栅传感系统的应用需求。A novel large capacity fiber grating sensor demodulation system with tunable narrow source, which uses optical wavelength division multiplex and space division multiplex technology, was designed. The experiment result shows that the novel system could realize realtime monitoring on multiple sensor point in parallel. Higher system capacity and better SNR are realized in the experiments compared with the traditional demodulation solution.
