Modern gyroscope is an instrument that can accurately determine the orientation of moving objects. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and defense industries. It develops for a country's industry, defense and other industries. The development of high technology is of great strategic importance. The traditional inertial gyro mainly refers to the mechanical gyroscope. The mechanical gyroscope has high requirements on the process structure and the structure is complex, and its precision is restricted by many aspects. Since the 1970s, the development of modern gyroscopes has entered a new stage. In 1976, scientists proposed the basic idea of modern fiber optic gyroscopes. After the 1980s, modern fiber optic gyroscopes developed very rapidly, and at the same time, laser resonant gyroscopes have also developed greatly. The fiber optic gyroscope has the advantages of compact structure, high sensitivity, reliable operation and the like. In addition to the ring laser gyro, there is also a modern integrated vibrating gyroscope developed by the fiber optic gyroscope. The integrated vibrating gyroscope has higher integration and smaller size, and is also an important modern gyroscope. Direction of development.
