The invention discloses a miniature dual-axis optical fiber gyroscope, which includes a housing and an optical fiber ring support structure, the optical fiber ring support structure is fixed inside the housing; the optical fiber ring support structure is an internal and external embedded optical fiber ring support structure, including: an optical fiber ring mounting bracket, Cooperating with the mounting bracket, the external embedded fiber ring and the embedded optical fiber ring; the optical fiber ring mounting bracket and the matching mounting bracket are orthogonal to each other and arranged in a square shape; the external embedded optical fiber ring and the internal optical fiber ring are arranged perpendicular to each other Inside the structure, and the diameter of the embedded optical fiber ring is larger than the diameter of the embedded optical fiber ring; four L-shaped mounting surfaces are formed around the well-shaped structure; the fiber optic gyroscope also includes circuit modules, system light sources, couplers, Y The waveguide and the twin-axis optical fiber that share the light source are respectively wound on the outer and inner fiber rings, and the circuit module, system light source, coupler and Y-waveguide are installed on the L-shaped mounting surface. The invention effectively reduces the volume of the fiber optic gyroscope on the premise of ensuring the application requirements of the fiber optic gyroscope.
Description
technical field [0001] The invention relates to the technical field of optical fiber sensing, in particular to a miniature dual-axis optical fiber gyroscope. Background technique [0002] Fiber optic gyroscope is an angular velocity sensor based on optical relativity. Compared with traditional rotor-type electromechanical gyroscopes and laser gyroscopes with "mechanical shaking" structures, fiber optic gyroscopes have truly achieved an all-solid-state structure design and can achieve extremely high reliability and design flexibility. [0003] In the usual fiber optic gyroscope application system, two to three single-axis fiber optic gyroscopes are generally combined by structural parts according to the coordinate axis direction, and then the technical functions such as angular velocity information reading and closed-loop control of the device are completed through circuits and software. Such designs generally have the problems of large volume, heavy weight, and complex stru...
