ABSTRACT:
A three-dimensional (3-D) display system using a variable focal length lens includes at least one two-dimensional (2-D) display device, configured to display at least one two-dimensional image. The display system also includes an array of micromirror array lenses optically coupled to the display device, each micromirror array lens of the array of micromirror array lenses placed at a different location with respect to the display device, configured to focus the at least one two-dimensional image from each different location to provide a three-dimensional (3-D) image. The advantages of the present invention include increased viewing angles and wide depth range of three-dimensional images.
