| 摘 要： | 分析了有源环形谐振腔组成的光纤激光陀螺的精度与谐振腔特征参数的关系,采用单向泵浦光纤复合谐振腔结构的光学系统设计方案.在此结构上,对影响光纤激光陀螺理论精度的结构参数进行计算机数值仿真,详细讨论了系统参数的变化趋势对光纤激光陀螺理论精度的影响.初步仿真结果表明:选取合适掺铒光纤长度及泵浦功率可以有效提高理论精度,提高输入信号光强及选择合适的输出耦合器的耦合比,可进一步提高陀螺的理论精度.

| Abstract: | Active fiber ring resonator is the key part of a fiber resonant laser gyroscope(FRLG) system.The measurement precision of FRLG is decided by the active resonator performance.The theoretical precision of a fiber resonant laser gyro is changed with different parameters of the active resonator,which can be achieved by including a fiber amplifier in the ring.According to the structure of FRLG,the effect of parameters of active resonator is investigated and discussed in detail.Simulation results showed that the ... |
