Patent ID: 7482730

Claim:
A MEMS scanner; comprising: a scan plate having longitudinal and lateral dimensions; a first torsion arm coupled to the scan plate and extending longitudinally from a proximal to a distal location therefrom, the first torsion arm defining an axis of rotation of the scan plate; a first leverage member coupled to the distal location of the first torsion arm and extending laterally therefrom in opposing directions from an axial location coincident with the first torsion arm to two lateral locations, the lateral locations forming junctions with one or more mounting structures; wherein the first torsion arm and the first leverage member each have about the same cross-sectional area and the first leverage member is configured to reduce stress in the torsion arm; and wherein the scan plate is coupled to the first torsion arm via a scan plate mounting structure, the scan plate mounting structure comprising: a suspension beam coupled to the first torsion arm at a location of the suspension beam generally coincident with the axis of rotation, and further coupled to the scan plate at one or more points not coincident with the axis of rotation; and an axial connector coupling the suspension beam with the scan plate at a location generally coincident with the axis of rotation.
