US Patent 7403322 - Micromirror alignment platform

Micromechanical mirrors have been developed over the past several decades in applications such as fiber optic switching, projection displays, 3D imaging, and adaptive optics. In many of these applications alignment between the light source and the micromirrors can be critical. This patent from Lucent Technologies teaches a common positioning stage provided for a plurality of micromirrors to facilitate such alignment. Claim 1 reads:

1. A MEMS device, comprising:

a stationary part; and

a movable part movably connected to the stationary part, wherein the movable part comprises a platform and a plurality of mirrors mounted on the platform, wherein: each mirror is adapted to move with respect to the platform; and the platform is adapted to translate with respect to the stationary part.
