Abstract
A novel and low-cost noncontact solution is realized for measuring the resonator frequency of vibration by using a sensitive microphone. This hemispherical resonator is operated at a specific mode (mode 2), which is useful for the Coriolis vibratory gyroscope applications. This mode of vibration is excited in the resonator by using electrostatic force. The experiments were conducted to measure vibrational frequency of the hemispherical metallic resonator by using the proposed method. It is observed that the experimental results are in good agreement with the simulated results.
