Abstract

A laser scanning assembly includes a coil support element having a central axis about which is wound an electromagnetic wire coil and having a flange oriented generally transverse to the central axis. An elastomeric flexural element 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 flexural element. 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 coil support element. The elastomeric flexural element 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.

Dependent claims

A laser scanning assembly for use in scanning a light beam generated from a light source such a laser source, comprising:

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