MULTI-FOCAL DISPLAY SYSTEM AND METHOD
First Claim
1. An augmented reality display system, comprising:
- a scanning device for scanning one or more frames of image data, wherein the scanning device is communicatively coupled to an image source to receive the image data;
a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens, and the plurality of switchable screens spreads light associated with the intermediate image plane to specific viewing distances; and
viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.

Abstract
Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a scanning device for scanning one or more frames of image data. The scanning device may be communicatively coupled to an image source to receive the image data. The system may further comprise a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens. The plurality of switchable screens may spread light associated with the intermediate image plane to specific viewing distances. The system may also comprise viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.

13. A method of displaying augmented reality, comprising:
-
providing one or more frames of image data; scanning light associated with the one or more frames of image data in a scanning pattern; varying the focus of the scanned light, through a variable focus element (VFE), such that the one or more frames of image data is brought into focus on one of plurality of switchable screens; and spreading the focused light, through the one of the plurality of switchable screens, wherein the switchable screens correspond to different viewing distances. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 23)

24. An augmented reality display system, comprising;
-
a scanning device operatively coupled to an image source for scanning an image in a scanning pattern; a variable focus element (VFE) operatively coupled to the scanning light display to variably focus the image; and a processor coupled to the VFE to vary a drive signal of the VFE as a function of the scanning pattern of the display in order to produce a substantially flat image field to correct a field curvature of the image. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
