Abstract
A piezoelectric actuator for rotating a shaft associated with an optical mount positioning system in which the actuator moves in first direction at a slow enough velocity to maintain engagement between the actuator and shaft to drive the shaft in the desired direction, and the actuator moves in a second direction at a sufficiently high acceleration and velocity to cause the actuator to lose engagement with the shaft and slip, thereby achieving motion of the shaft in only the desired direction.
