摘要
介绍了光纤振动传感器的定义及其类别。对相位生成载波(PGC)技术、3×3耦合器解调算法和数字正交解调算法3种光纤振动传感器相位解调算法进行了对比和分析,指出后期相位解调算法仍然有很多改进的方面。最后介绍了未来在实际中有望得到更广泛的应用的情况。
First,the definition of fiber optic vibration sensors and types are introduced.Second,the principles of each demodulation algorithm are analysized which mainly includes:phase generation carrier(PGC)technology,3×3 coupler demodulation algorithm,digital orthogonal demodulation algorithm.Finally,the advantages and disadvantages are compared and summarized,which pointed out that there are still many improvements in the phase demodulation algorithm in the later stage,and it is expected to obtain wide application in the future.
