Patent ID: 7463342

Claim:
An optical tracking device, comprising: (a) a lens unit comprising at least one Micromirror Array Lens, wherein the Micromirror Array Lens comprises a plurality of micromirrors and is configured to have a plurality of optical surface profiles by controlling rotations or translations of the micromirrors, wherein the motions of micromirrors in the Micromirror Array Lens is controlled to correct aberration; (b) a control circuitry, communicatively coupled to the lens unit, configured to control the motions of micromirrors in the Micromirror Array Lens to form optical surface profiles for changing a focusing property of the lens unit; and (c) an imaging unit comprising at least one image sensor, optically coupled to the lens unit, configured to receive a scene image formed by the lens unit to generate image information of the scene image.
