Miniature optical fiber gyroscope

The utility model relates to a miniature optical fiber gyroscope, which comprises an outer cover at an upper part and a ring body at a lower part. The upper half part of the outer cover is a cylinder. The bottom of the outer cover is a flange and is assembled with the ring body. The upper part of the ring body is a cylinder and the lower part of the ring body is a rectangular parallelepiped. The diameter of the upper part of the ring body is smaller than the diameter of the flange at the bottom of the outer cover. A photoelectric device coupler and a Y waveguide are installed at the upper part of the ring body. An optical fiber ring is wound on the periphery of the ring body. The internal part of the ring body is used for the installation of other photoelectric devices and a circuit board. The bottom surface of the ring body is an optical fiber gyroscope installation surface. The miniature optical fiber gyroscope has the advantages of small size, compact structure and reliable performance, the miniaturization
