摘要
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 。
A simple optical field overlap method is reported to calculate the transfer coefficient of fiber ring resonator, the heart of the resonator fiber optic gyro. The results are applied to the investigation of influence of spectral linewidth of laser on resonance characteristics in fiber ring resonator. Furthermore, analysis has been made of relationship between the shot-noise-limited sensitivity of resonator fiber optic gyro and optical parameters in fiber ring resonator under some spectral linewidth of the laser conditions. The results are provided to theoretical basis for optimization design of resonator fiber optic gyro.
