摘　　要：对谐振式光纤陀螺中全保偏环形谐振腔及其定向耦合器进行了理论和实验研究，推导了谐振条件的解析表达式，并分析了谐振腔基本参数对谐振特性的影响。通过压电陶瓷对光纤谐振腔进行调制，记录输出特性曲线，得到了保偏环形谐振腔的谐振特性。最后给出了实验结果及测试曲线。并提出了在谐振系统中应加以解决的问题，为下一步系统的工作奠定了理论及实验基础。The theoretical and experimental study of the polarization maintaining (PM) ring resonator and its fiber directional couplers in the resonant fiber gyroscope are reported. The analytic equations of resonant conditions are deduced and the contribution of the resonator's basic parameters to the resonant performance is also analyzed. By modulating the fiber ring resonator using piezoelectric element, the resonant output is recorded. And the resonant characteristics of the PM ring resonator are obtained. At last the experimental results and a testing curve are given. And several problems to be solved in the resonant system are also proposed, which build the theoretical and experimental base of the study in the next stage.
