technical field [0001] The invention belongs to the technical field of inertial measurement sensors, in particular to a spectral confocal-based hemispherical resonant gyro precision assembly device and an adjustment method thereof. Background technique [0002] The hemispherical resonant gyroscope is a new type of inertial solid gyroscope, which has unique advantages such as high precision, small size, strong impact resistance, long life and high reliability, and has obvious advantages in military applications. The hemispherical resonator gyroscope is mainly composed of two core functional components, the hemispherical resonator and the base electrode. Generally, electrostatic excitation and capacitance detection are used to realize the control and detection of the standing wave in the resonator. The uneven gap between the resonator and the base electrodes during assembly will not only lead to inconsistent capacitance values ​​between the electrodes of the gyroscope, but als...

AI Technical Summary

Problems solved by technology

Since both the resonator and the base are spherical, and the gap between the two is small and the gap consistency is high, it cannot be measured by traditional contact measurement methods

Both the resonator and the base are plated with gold, and the gap cannot be directly measured by optical measurement.

In addition, due to the technical blockade, there are currently no relevant reports on the precision assembly technology of resonant gyroscopes

To sum up, the precise alignment of the sphere center between the resonator and the base electrode is of great significance for the development of high-precision hemispherical resonant gyroscopes. However, this technology is relatively difficult, and there is currently no solution for reference.
