Abstract
Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a spatial light modulator operatively coupled to an image source for projecting light associated with one or more frames of image data, 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.
