摘　　要：提出了一种新型结构的光纤陀螺 ,它将起偏器和两只定向耦合器集成在一块由两只光轴方向相互成 45°角胶合而成的冰洲石晶体上。同传统集成型光纤陀螺 (IFOG)相比 ,它具有结构简单、性能稳定、损耗小、体积小、成本低的特点。详细分析了它的工作原理 。A novel structure fiber optical gyro is proposed. It consists of a pair of calcite crystals oriented by 45° and adhered together, in which a polarizer and two directional couplers are integrated. Comparing with traditional IFOG, it has the advantages of simple structure, stability, small volume and low cost. The operation principle and method for signal detection are theoretically analyzed.
