1. An apparatus comprising:
- a display device comprising a plurality of pixels;
a computer system coupled with said display and operable to instruct said display to display images;
a spatial light modulator (SLM) array located adjacent to said display and comprising a plurality of spatial light modulators (SLMs); and
a light shutter operable to block rays of light originating from a surrounding environment from entering said display device and said SLM array when said display device and said SLM array are operating,wherein said SLM array is operable to produce a light field by altering light emitted by said display device to simulate an object that is in focus to an observer while said display device and said SLM array are located within a near-eye range of said observer, and wherein said SLM array comprises an array of high-speed SLMs operable to refresh at a faster rate than a flicker fusion threshold for a human eye.

Abstract
In embodiments of the invention, an apparatus may include a display comprising a plurality of pixels and a computer system coupled with the display and operable to instruct the display to display images. The apparatus may further include an SLM array located adjacent to the display and comprising a plurality of SLMs, wherein the SLM array is operable to produce a light field by altering light emitted by the display to simulate an object that is in focus to an observer while the display and the SLM array are located within a near-eye range of the observer.

11. An apparatus comprising:
-
a display device operable to produce an image; a first SLM array located adjacent to said display device; and a light shutter operable to block rays of light originating from a surrounding environment from entering said display device and said first SLM array when said display device and said first SLM array are operating, wherein said first SLM array together with said display device is operable to produce a light field simulating a 3D object that is recognizable to an observer while said display device and said first SLM array are located within a near-eye range of said observer, and wherein said first SLM array comprises an array of high-speed SLMs operable to refresh at a faster rate than a flicker fusion threshold for a human eye. - View Dependent Claims (12, 13, 14, 15, 16, 17, 25)

18. A method comprising:
-
determining a pre-filtered image to be displayed, wherein said pre-filtered image corresponds to a target image; displaying said pre-filtered image on a display device; and producing a near-eye light field after said pre-filtered image travels through an SLM array adjacent to said display device, wherein said near-eye light field is operable to simulate a light field corresponding to said target image, wherein a light shutter disposed in an apparatus comprising said SLM array and said display device is operable to block rays of light originating from a surrounding environment from entering said SLM array and said display device when said SLM array and said display device are operating, and wherein said SLM array comprises an array of high-speed SLMs operable to refresh at a faster rate than a flicker fusion threshold for a human eye. - View Dependent Claims (19, 20, 21, 22, 23, 26)
