| 摘 要： | 本文提出了一种采用电光移频器和高双折射光纤构成的新型外差检测方式的光纤陀螺方案。它既能改善通常外差光纤陀螺中存在的光路非互易性且无需使用声光器件,又能避免采用高双折射光纤的直接检测光纤陀螺中电子线路直流漂移的影响。初步实验的结果显示出该系统具有良好的定标因子线性度。

| Abstract: | In this paper, a novel fiber-optic heterodyne detection technique of rotation rate is described. Using electro-optic frequency shifter and highly birefringent single-mode fiber, the heterodyne fiber-optic gyroscope system no more needs the use of acousto-optic devices and is free from the direct-current drift in the electronics. In addition, the reciprocity of the optical path in the system is improved. Preliminary experiments have shown a good linearity of the scale factor |
