光纤陀螺
摘要：
本发明涉及一种光纤陀螺，包括Y波导、光纤环和消偏器，其中消偏器设置在Y波导和光纤环之间，光纤环和Y波导采用单模光纤制成。由于同样长度的保偏光纤价格是单模光纤的约50倍以上，且采用三个保偏光纤作为尾纤的Y波导其制造工艺复杂、成品率低等原因导致传统的Y波导成本高昂，而本实施例中则通过采用单模光纤制成光纤环和Y波导、并在光纤环和Y波导之间设置消偏器来代替采用保偏光纤制成光纤环和Y波导，从而大大降低了光纤陀螺的成本。
摘要（英）：

The invention relates to an optical fiber gyroscope which comprises a Y waveguide, an optical fiber ring and a depolarizer, wherein the depolarizer is arranged between the Y waveguide and the opticalfiber ring; the optical fiber ring and the Y waveguide are made of single-mode optical fibers. The price of polarization maintaining optical fibers with the same length is above 50 times than the price of the single-mode optical fibers, and the traditional Y waveguide is high in cost as the Y waveguide adopting three polarization maintaining optical fibers as tail fibers is complex in manufacturing process, low in yield and the like; in the embodiment, the manufacturing manner that the optical fiber ring and the Y waveguide are made of the polarization maintaining optical fibers is replaced bythe manufacturing manner that the optical fiber ring and the Y waveguide are made of the single-mode optical fibers, and the depolarizer is arranged between the optical fiber ring and the Y waveguide, so that the cost of the optical fiber gyroscope is greatly lowered.
