采用光波场叠加的方法计算了谐振腔光纤陀螺的核心敏感部件———光纤环形谐振腔 (FRR)的传递系数 ,详细分析了激光器光谱线宽对光纤环形谐振腔谐振特性的影响 ,并进一步分析了在一定激光器光谱线宽条件下 ,由光探测器散弹噪声所限制的谐振腔光纤陀螺极限灵敏度和光纤环形谐振腔光路参数之间的关系 ,从而为谐振腔光纤陀螺的优化设计提供了理论基础
The transmission coefficient of the fiber ring resonator (FRR), which is the core sensitive component of the resonator fiber optic gyroscope, was calculated by superposition of optical wave fields. The influence of the laser linewidth on the resonance characteristics of the fiber ring resonator was analyzed in detail and further analyzed The relationship between the limit sensitivity of optical fiber gyroscope and the optical path parameters of optical fiber ring resonator limited by the shot noise of the optical detector under certain laser linewidth is provided to provide the theory for the optimal design of resonator fiber optic gyroscope basis
