摘要: An optical scanning or positioning mechanism has a head on which optical components are mounted and an actuator coupled to the head to cause the head to move when the actuator is actuated. There are one or more sets of flexure bearings mounted in the mechanism. The flexure bearings have a restoring torque when moved from a rest position. The bearings are coupled to the head to allow the head to move when actuated by the actuator. One or more magnets are mounted in the mechanism in a location other than in the actuator to compensate for the flexure bearings restoring torque.
