1. An augmented reality display system, comprising:
- first and second spatial light modulators operatively coupled to an image source for projecting light associated with one or more frames of image data, wherein the first spatial light modulator comprises a Digital Light Processing system that provides grayscale images and the second spatial light modulator comprises a Liquid Crystal Display that provides a color map, the combination of the Digital Light Processing system and the Liquid Crystal Display work in conjunction to create multiple depth planes; and
a variable focus element (VFE) for varying a focus of the projected light such that a first frame of image data is focused at a first depth plane, and a second frame of image data is focused at a second depth plane, and wherein a distance between the first depth plane and the second depth plane is fixed,wherein the first and second spatial light modulators are disposed along a same optical path.
