The invention provides an optical fiber gyroscope, and relates to the field of gyroscopes. The optical fiber gyroscope comprises a shell, a light source, a first coupler and three groups of fiber-optic gyroscopes which arranged in the shell, light emitted by the light source is divided into three beams of light after passing through the first coupler, and the three beams of light enter the three groups of optical fiber gyroscopes respectively; each group of optical fiber gyroscopes comprises a second coupler, a Y waveguide, an optical fiber ring, a photoelectric detector and a signal processing circuit which are connected in sequence; an integrated design technology is adopted in optical fiber inertial navigation, namely, three optical fiber gyroscopes are driven by one light source, so that the problems of light source stability and parameter consistency are effectively solved, and key technologies such asa three-axis multiplexing light path anti-cross interference technology, a miniaturized integration technology and quick start of the optical fiber gyroscope are avoided, the cost is saved, the size is reduced, the starting time of the system is shortened, the reliability of the system is improved, and the system has vibration and impact resistance.
Description
Technical field [0001] The present invention relates to the field of gyroscope, and in particular, there is a fiber optic gyroscope. Background technique [0002] The traditional inertial gyroscope mainly refers to the mechanical gyroscope, the mechanical gyroscope requires high requirements, the structure is complicated, and its accuracy has been constrained in many ways. Since the 1970s, the development of modern gyroscopes has entered a new stage. Modern fiber optic gyroscope is an instrument capable of accurately identifying the orientation of sports objects. It is a widely used inertial navigation instrument in modern aviation, navigation, aerospace and defense industries. Its development is the industry, defense and other other people. The development of high-tech is very important. [0003] The implementation of the fiber optic gyroscope is based primarily based on the Serenk theory: When the beam travels in a ring-shaped channel, if the ring channel itself has a rotationa...
