Abstract

Piezoelectric discs are mounted within conical members, one of which is contact with a mirror. Electrodes are applied across the piezoelectric discs. Voltage applied to the electrodes cause the diameter of the disc to contract deforming the conical members and moving the mirror. The conical members provide mechanical amplification resulting in mirror movements to control the path length in a ring laser gyroscope.
