ABSTRACT:
A scan element includes a bobbin having a central axis about which is wound an electromagnetic wire coil and having a flange oriented generally transverse to the central axis. At least one elastomeric support has a first end coupled to the flange. A permanent magnet has first and second surfaces, a central axis, and a magnetization direction oriented generally transverse to the central axis of the permanent magnet. The magnet is supported by a second end of the elastomeric support. A mirror has a central axis and is mounted on the second surface of the magnet. The central axes of the mirror and magnet are coaxial with the central axis of the bobbin. The elastomeric support provides a return force when the magnet and the mirror are rotated at an angle from the central axis during energization of the electromagnetic wire coil.
