ABSTRACT:
The optical tracking device of this invention comprises a lens unit, a control circuitry communicatively coupled to the lens unit, and an imaging unit optically coupled to the lens unit. The lens unit comprises 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. The optical tracking device of the invention further comprises an image processing unit, communicatively coupled to the imaging unit, configured to process the image information from the imaging unit and generates a control signal for the control circuit to control the lens unit. The optical tracking device of the present invention provides capability of tracking a target moving in a high speed, providing three-dimensional image information of the object, and compensating the aberration of the optical tracking device.
