METHODS AND SYSTEMS FOR DISPLAYING STEREOSCOPY WITH A FREEFORM OPTICAL SYSTEM WITH ADDRESSABLE FOCUS FOR VIRTUAL AND AUGMENTED REALITY
First Claim
1. A tiled freeform optical display system, comprising:
- an image source injecting light rays into a primary freeform optical element;
a secondary freeform optical element coupled directly with no intervening elements or indirectly with one or more intervening elements to the primary freeform optical element in a first tiled arrangement to form a tiled freeform optical display device for displaying virtual display content with at least a portion of the light rays from the image source; and
a variable focusing element coupled directly with no intervening elements or indirectly with one or more intervening elements to the image source and the tiled freeform optical display device to change a focal distance of a focal plane on which at least a part of the virtual display content is rendered in focus.

Abstract
Several unique hardware configurations and methods for freeform optical display systems are disclosed. A freeform display system includes primary freeform optical element(s) and secondary freeform optical element(s) in tiled arrangements to expand the horizontal field of view (FOV) or the vertical field of view. The system may include a variable focusing system that produces intermediate pupil and changes the focal distance of a single focal plane or switches among multiple focal planes for rendering objects in focus while resolving accommodation-convergence conflict. The system may map light samples to appropriate light rays in physical space and use a cluster of projectors to project the mapped light rays to produce the light field of the virtual display content. Methods for making tiled freeform optical display systems and methods for producing virtual content with variable focus freeform optics and rendering light fields are also disclosed.

36. A method for generating stereoscopic images with a variable focusing freeform optical display system for virtual or augmented reality, comprising:
-
receiving input light beams at an optical system from an image source; altering a focal length of a variable focus mechanism for the input light beams based in part or in whole upon positioning of at least one focal plane for the stereoscopic images; propagating the input light beams by using at least the variable focus mechanism with an altered focal length to a freeform optic mechanism; and generating the stereoscopic images on the at least one focal plane for a virtual or augmented reality presentation with the freeform optic mechanism. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45)
