1. A three-dimensional imaging system for robot vision comprising:

  • (a) a lens system, comprising a variable focal length micromirror array lens (MMAL), configured to change the focal plane by changing the focal length of the variable focal length MMAL;

    (b) an imaging unit, optically coupled to the lens system, configured to receive an object image from the lens system and to sense the object image; and

    (c) an image processing unit, communicatively coupled to the imaging unit, configured to process the object images sensed by the imaging unit and to generate an all-in-focus image and three-dimensional position information of the object.
