Physical actuators coupled to optical fiber cores 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, comprising;
 an array of optical fiber cores to transmit light beams associated with an image to be presented to a user; and   a lens coupled to the array of the optical fiber cores to deflect a plurality of light beams output by the array of optical fiber cores through a single nodal point, wherein the lens is physically attached to the optical fiber cores such that a movement of the optical fiber core causes the lens to move, and wherein the single nodal point is scanned.   
     
     
         2 . The system of  claim 1 , wherein the light beams output by the array of optical fiber cores represents a pixel of the image to be presented to the user. 
     
     
         3 . The system of  claim 1 , wherein the lens is a GRIN lens. 
     
     
         4 . The system of  claim 1 , where the array of optical fiber cores is used to display a lightfield. 
     
     
         5 . The system of  claim 1 , wherein another set of light beams output by another array of optical fiber cores represents another pixel of the image to be presented to the user. 
     
     
         6 . The system of  claim 1 , wherein multiple arrays of optical fiber cores are combined to represent a pixel of the image to be presented to the user. 
     
     
         7 . The system of  claim 1 , wherein the array of optical fiber cores is configured to deliver the light beams to a predetermined portion of the user's pupil. 
     
     
         8 . The system of  claim 1 , wherein the output light beams are diverging. 
     
     
         9 . The system of  claim 1 , wherein the output light beams are converging. 
     
     
         10 . The system of  claim 1 , wherein a numerical aperture of the output light beams is increased relative to the light beams transmitted by the individual optical fiber cores. 
     
     
         11 . The system of  claim 10 , wherein the increased numerical aperture allows for higher resolution. 
     
     
         12 . The system of  claim 1 , wherein the array of optical fiber cores is beveled in a manner such that a path length of a first light beam traveling through a first optical fiber is different than a second light beam traveling through a second optical fiber, thereby allowing for a plurality of focal lengths of the light beams delivered to the user's eye. 
     
     
         13 . The system of  claim 1 , wherein the optical fiber cores are in a same fiber cladding. 
     
     
         14 . The system of  claim 1 , wherein the optical fiber cores are in separate fiber claddings.
