Inducing phase delays in a multicore assembly 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 method for displaying virtual content to a user, comprising:
 emitting light through a multicore fiber, the multicore fiber comprising a plurality of single core fibers, wherein the singlecore fibers emit a spherical wavefront;   providing an aggregate wavefront from light emitted from the plurality of single core fibers; and   inducing a phase delay between the singlecore fibers of the multicore fiber such the aggregate wavefront produced by the multicore fiber is varied based at least in part on the induced phase delay.   
     
     
         2 . The method of  claim 1 , wherein the aggregate wavefront is a planar wavefront. 
     
     
         3 . The method of  claim 2 , wherein the planar wavefront corresponds to optical infinity. 
     
     
         4 . The method of  claim 1 , wherein the aggregate wavefront is spherical. 
     
     
         5 . The method of  claim 4 , wherein the spherical wavefront corresponds to a depth plane closer than optical infinity. 
     
     
         6 . The method of  claim 1 , further comprising injecting an inverse Fourier transform of a desired wavefront into the multicore fiber such that the aggregate wavefront corresponds to the desired wavefront. 
     
     
         7 . The method of  claim 1 , wherein wavefronts generated by the plurality of singlecore fibers interfere with each other. 
     
     
         8 . The method of  claim 7 , wherein the interference is a constructive interference. 
     
     
         9 . The method of  claim 7 , wherein the interference is a destructive interference. 
     
     
         10 . The method of  claim 1  implemented as a system having means for implementing the method steps.
