Abstract
A piezoelectric actuator for use in controlling the path length, for example, in a ring laser gyro is made of two piezoelectric discs attached to a metallic structure for exerting a push-pull force thereon to move the metallic structure in an oil can fashion. The piezoelectric actuator is attached to a dual diaphragm mirror assembly in such a way as to impart a strictly linear motion to the mirror assembly without any deliterious rotational effects. The actuator can easily be optimized for varying diaphragm stiffness by adjusting the thickness of the metallic structure to which the piezoelectric discs are attached. The mirror assembly and actuator are designed to minimize the influence of temperature changes on the position of the path length mirror.
