Systems and methods of providing improved performance of scanning mirrors coupled to limited rotation motors
First Claim
1. A mirror for use in a limited rotation motor system, said mirror comprising:
- a body formed of at least one material and having an exposed mirror surface, said body being mountable with the limited rotation motor system for rotation with respect to an axis of mirror rotation;
an aperture within the body of the mirror, said aperture being at least proximate to a portion of said axis of mirror rotation; and
a high density material within said aperture and capable of movement within said aperture with respect to the body of the mirror, said high density material having a density that is greater than a density of the at least one material of the body of the mirror.

Abstract
A mirror is disclosed for use in a limited rotation motor system, wherein the mirror includes a body, an aperture within the body, and a high density material within the aperture. The body, formed of one or more materials, has an exposed mirror surface and is mountable with the limited rotation motor system for rotation with respect to an axis of mirror rotation. The aperture is positioned at least proximate to a portion of the axis of mirror rotation. The high density material is provided within the aperture such that it is capable of movement within the aperture, and the high density material has a density that is greater than a density of the material of the body of the mirror.

9. A scanning system including a limited rotation motor coupled to a mirror, said limited rotation motor comprising a rotor shaft and said mirror comprising:
-
a body having an exposed mirror surface and being coupled to the rotor shaft of the limited rotation motor system for rotation with respect to an axis of mirror rotation; a high density material within an aperture in the body of the mirror, said high density material being capable of movement within said aperture with respect to the body of the mirror, and said high density material having a density that is greater than a density of the body of the mirror. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of damping vibrations in a scanning system that includes a limited rotation motor including a rotor shaft, and a mirror coupled to the rotor shaft of the limited rotation motor, said method comprising the steps of:
-
rotating the mirror about an axis of mirror rotation through application of a torque applied to the mirror by the limited rotation motor via the rotor shaft; and accelerating a high density material within the mirror due to vibrations in the movement of the minor, whereby the acceleration of the high density material within the mirror absorbs energy from the vibrations thereby damping vibrations in the scanning system. - View Dependent Claims (18, 19, 20)
