ABSTRACT:
A ring laser gyroscope is described that includes at least one laser gyroscope block and a dither motor, where the gyroscope blocks are configured to engage the dither motor. The dither motor has an outer ring, a hub section, at least one radially extending reed extending between the outer ring and the hub section, and at least one piezoelectric transducer attached the reed. The piezoelectric transducer includes a common piezo-ceramic having a contiguous void line that allows for a separate electrical connection to be made to electrode surfaces on each side of the void line.
