Abstract : A tilt mechanism includes a rigid base member, a first tilt plate pivotally mounted on the base member, and a second tilt plate pivotally mounted on the first tilt plate. The first and second tilt plates are pivoted via actuating mechanisms which include stepper motors. harmonic drives, and precision nuts which translate the rotational output of the harmonic drives to pivotal motion of the tilt plates. All of the movable components of the mechanism are mounted to one another via flexural pivots which allow at least limited rotation in one direction but which prevent movement in all other directions.
