AI Technical Summary
Existing angular sensors suffer from manufacturing defects leading to frequency anisotropy, which conventional methods like adjusting spring stiffness or using electrostatic springs fail to adequately address, especially in applications with strict manufacturing and precision constraints.
The angular sensor employs a vibrating resonator with concentric masses connected by mechanical springs arranged in pairs forming 45° angles, allowing for adjustable frequency anisotropy compensation without the need for electrostatic springs, achieved through symmetric spring orientation and localized adjustments in stiffness.
This configuration effectively reduces frequency anisotropy, enhancing sensor accuracy by allowing precise adjustment of spring stiffness in multiple directions, thus improving overall performance.
