Description

technical field [0001] The invention relates to the field of inertial measurement, in particular to an all-solid-state high-speed rotation measurement system based on an optical fiber structure. Background technique [0002] With the development of equipment technology and weapon platform technology, the development of high-reliability and high-performance inertial technology is inevitable. The new generation of equipment system has further improved the rotation speed. How to measure the large angular velocity under high-speed rotation while maintaining Smaller resolution and high sensitivity become problems faced by inertial measurement systems. [0003] Traditional mechanical gyroscopes have moving parts such as high-speed rotors, which make them vulnerable to shocks and strong sensitivity to G and G2. However, the centripetal acceleration brought by high-speed rotation is proportional to the square of the rotational angular velocity, which together limits the The rotatio...

Problems solved by technology

[0004] However, up to now, there are not many domestic units conducting research on high-speed rotating inertial measurement devices. Most of the research is still in the stage of laboratory prototypes, and almost all of the research is based on the combination of discrete gyroscopes and additional meters, which is not conducive to system development. In addition, the gyro and the meter are installed in three mutually perpendicular directions, and each gyro and meter is a complete body, each sensitive to the inertial data in the three orthogonal directions, increasing the The volume and power consumption of the system require data integration and processing at the data terminal, which limits the development of inertial measurement systems and high-speed rotating equipment systems
