Vibrating beam accelerometer
Abstract:
Systems and methods for improving common mode cancelation in a vibrating beam accelerometer (VBA) by using multiple resonant modes. The VBA includes two double-ended tuning forks (DETF). Additional oscillators drive the DETFs into the extra resonant modes. This increases common mode rejection from two modes to four modes. In addition the scale factor of the additional mode may provide a greater scale factor than prior designs.
