摘要

介绍了利用铁电材料调节机械质量因子的动态质量因子均衡。对四分之三的测量样品,将初始质量因子分割率控制在~ 10%以内,控制在0.27%以内。该机制有望提高模式匹配陀螺仪的偏置稳定性,可以集成到微机模式匹配陀螺仪中,甚至可以集成到宏观模式匹配陀螺仪中,实现电子控制的退化模式之间的机械品质因子匹配。

Dynamic Quality Factor Equalization for Improved Bias Stability in Mode-Matched Gyroscopes
Dynamic quality factor equalization using ferroelectric materials to tune mechanical quality factor is demonstrated. An initial quality factor split of ~ 10% was controlled to less than 0.27% for three quarters of measurement samples. This mechanism is promising for improving bias stability in mode-matched gyroscopes and can be integrated into microelectromechanical mode-matched gyroscopes, or even macro-scale mode-matched gyroscopes to realize electronically controlled mechanical quality factor matching between degenerate modes.
