USING FREEFORM OPTICAL ELEMENTS TO DISPLAY AUGMENTED OR VIRTUAL REALITY
Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image-generating source to provide one or more frames of image data in a time-sequential manner, a light modulator configured to transmit light associated with the one or more frames of image data, a substrate to direct image information to a user's eye, wherein the substrate houses a plurality of reflectors, a first reflector of the plurality of reflectors to reflect transmitted light associated with a first frame of image data at a first angle to the user's eye, and a second reflector to reflect transmitted light associated with a second frame of the image data at a second angle to the user's eye.
1 . A system comprising:
an image generating source to provide one or more frames of image data to be presented to a user;
a display system to provide light associated with the one or more frames of image data, wherein the display system comprises a plurality of microdisplays; and
a free form optical element to modify the provided light and deliver the light to the user.
2 . The system of claim 1 , wherein one or more freeform optics are tiled in relation to one another.
3 . The system of claim 1 , wherein the light projected by the plurality of microdisplays increases a field of view.
4 . The system of claim 1 , wherein the freeform optical elements are configured such that only one color is delivered by a particular freeform optical element.
5 . The system of claim 4 , wherein the tiled freeform is a star shape.
6 . The system of claim 4 , wherein the tiled freeform optical elements increase a size of an exit pupil.
7 . The system of claim 1 , further comprising another free form optical element, wherein the freeform optical element and stacked together in a manner to create a uniform material thickness.
8 . The system of claim 1 , further comprising another free form optical element, wherein the other optical element is configured to capture light corresponding to an outside environment.
9 . The system of claim 1 , further comprising a DMD, wherein the DMD is configured to occlude one or more pixels.

13 . The system of claim 1 , wherein the at least one image source includes at least a first monochromatic image source that provides light of a first color, at least a second monochromatic image source that provides light of a second color, the second color different from the first color, and at least a third monochromatic image source that provides light of a third color, the third color different from the first and the second colors.
14 . The system of claim 13 , wherein the at least a first monochromatic image source comprises a first subgroup of scanning fibers, the at least a second monochromatic image source comprises a second subgroup of scanning fibers, and the at least a third monochromatic image source comprises a third subgroup of scanning fibers.
15 . The system of claim 1 , further comprising:
an occluder positioned in an optical path between the first freeform reflective and lens optical component and the at least one reflector, the occluder operable to selective occlude light on a pixel-by-pixel basis.
16 . The system of claim 15 , wherein the first freeform reflective and lens optical component forms at least a portion of a contact lens.
