Description

technical field [0001] The invention belongs to the technical field of integrated optics and inertial sensors, in particular to a two-axis optical gyroscope. Background technique [0002] Optical gyroscopes are important test components for inertial navigation, inertial guidance and control testing equipment. The optical gyroscope is a new type of photoelectric gyroscope based on the Sagnac effect, and the development of its technology is closely related to the development of the gyroscope. The performance of the inertial guidance system largely depends on the performance of the gyroscope. Therefore, the technical level of the gyroscope directly affects the performance indicators of the inertial navigation system and the inertial guidance device. At present, the optical gyroscope in the application mainly realizes the single-axis measurement function, which has a single function and cannot realize the simultaneous measurement of multi-axis space. The development and resear...
