Delivering light beams through optical fiber cores at a plurality of angles for augmented or virtual reality

Abstract

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.

What is claimed is: 
     
         1 . A system for displaying virtual content to a user, comprising:
 an image-generating source to provide one or more frames of image data;   a plurality of optical fiber cores to transmit light beams associated with the one or more frames of image data; and   an optical element coupled to the plurality of optical fiber cores to receive collimated light from the optical fiber cores and deliver the light beams to the user's eye, wherein the light beams are delivered at a plurality of angles to the user's eye such that a first light beam is delivered to a portion of a user's eye at a first angle, and a second light beam is delivered to the same portion of the user's eye at a second angle, wherein the first angle is different from the second angle.   
     
     
         2 . The system of  claim 1 , wherein the optical element is a waveguide. 
     
     
         3 . The system of  claim 1 , further comprising a phase modulator to modulate the transmission of light through the optical fiber cores. 
     
     
         4 . The system of  claim 1 , wherein the plurality of angles affects a wavefront that is delivered to the user's eye. 
     
     
         5 . The system of  claim 1 , wherein the one or more optical fibers is coupled to a GRIN lens. 
     
     
         6 . The system of  claim 1 , wherein the plurality of optical fibers cores is physically actuated. 
     
     
         7 . The system of  claim 1 , wherein the optical element is a freeform optic. 
     
     
         8 . The system of  claim 1 , wherein the optical element is a substrate guided optic. 
     
     
         9 . The system of  claim 1 , wherein the optical element is a diffractive optic element. 
     
     
         10 . The system of  claim 1 , wherein the plurality of optical fiber cores are in the same fiber cladding. 
     
     
         11 . The system of  claim 1 , wherein the plurality of optical fiber cores are in separate fiber claddings. 
     
     
         12 . The system of  claim 1 , wherein a perceived focus of the light delivered at the first angle is different from the perceived focus of the light delivered at the second angle.
