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.
