|
摘要
设计了用于谐振式光纤陀螺系统中两个半导体激光器相对频率噪声抑制的全光纤光路外差式光学锁相环,建立并分析了陀螺精度需求和外差式光学锁相环关键参数的关系,同时对外差式光学锁相环全数字反馈控制环路进行了设计和仿真.通过实验对设计的系统进行性能验证.结果表明两个主从激光器的中心频率实现了参考频率源频率的锁定,且拍频激光中心频率相对于光纤环形谐振腔谐振频率偏离幅值减小了15dB.
A heterodyne all-fiber optical phase-locked loop is designed to suppress the relative frequency noise of two semiconductor lasers in passive resonator fiber gyros.The relationship between the bias stability of the passive resonator gyros and parameters of the optical phase-locked loop is established and analyzed.Then the mathematical model of the heterodyne digital optical phase-locked loop is built and simulated.Finally,the performance of the designed system is validated with experiments.Which generate a remarkable meaning of the multi-laser system used for all-fiber passive resonator gyros.The frequency difference between the two lasers is locked to the frequency of the reference source,and the deviation amplitude between the beat frequency of the lasers and the resonance frequency of the fiber ring resonator is successfully reduced by more than 15 dB.
