Coupling phase modulators to optical fibers 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 virtual reality display system comprising:
 a plurality of optical fiber cores to generate light beams associated with one or more images to be presented to a user; and   a plurality of phase modulators coupled to the plurality of optical fiber cores to modulate the light beams, wherein the plurality of phase modulators modulate the light in a manner that affects a wavefront generated as a result of the plurality of light beams.   
     
     
         2 . The virtual reality display system of  claim 1 , wherein one or more optical fiber cores are deflected, at one or more angles. 
     
     
         3 . The virtual reality display system of  claim 1 , wherein an optical fiber of the plurality of optical fiber cores is coupled to a GRIN lens. 
     
     
         4 . The virtual reality display system of  claim 1 , wherein the plurality of optical fiber cores is physically actuated to scan the optical fiber cores. 
     
     
         5 . The virtual reality display system of  claim 1 , further comprising an optical element coupled to the plurality of optical fiber cores for modifying the plurality of light beams. 
     
     
         6 . The virtual reality display system of  claim 5 , wherein the optical element comprises a waveguide. 
     
     
         7 . The virtual reality display system of  claim 5 , wherein the optical element comprises a freeform optic. 
     
     
         8 . The virtual reality display system of  claim 5 , wherein the optical element comprises a diffractive optical element. 
     
     
         9 . The virtual reality display system of  claim 5 , wherein the optical element comprises a substrate guided optic. 
     
     
         10 . The virtual reality system of  claim 1 , wherein the plurality of optical fibers are in the same fiber cladding. 
     
     
         11 . The virtual reality display system of  claim 1 , wherein the plurality of optical fibers are in separate fiber claddings.
