Injecting images having an inverse fourier transform to produce a desired wavefront

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, the system comprising:
 an image-generating source to provide one or more frames of image data;   a multicore assembly comprising a plurality of multicore fibers to project light associated with the one or more frames of image data;   an image injector to input images into the multicore assembly, wherein the input injector is further configurable to input an inverse Fourier transform of a desired wavefront into the multicore assembly such that the multicore assembly outputs the Fourier transform by producing light associated with the image data in the desired wavefront, thereby allowing the user to perceive the image data at a desired focal distance.   
     
     
         2 . The system of  claim 1 , wherein the desired wavefront is associated with a hologram. 
     
     
         3 . The system of  claim 1 , wherein the inverse Fourier transform is input to modulate a focus of the one or more light beams. 
     
     
         4 . The system of  claim 1 , wherein a multicore fiber of the plurality of multicore fibers is a multi-mode fiber. 
     
     
         5 . The system of  claim 1 , wherein the multicore fiber of the plurality of multicore fibers is configured to propagate light along a plurality of paths along the fiber. 
     
     
         6 . The system of  claim 1 , wherein the multicore fiber is a single core fiber. 
     
     
         7 . The system of  claim 1 , wherein the multicore fiber is a concentric core fiber. 
     
     
         8 . The system of  claim 1 , wherein the image injector is configured to input a wavelet pattern into the multicore assembly. 
     
     
         9 . The system of  claim 1 , wherein the image injector is configured to input a Zernike coefficient into the multicore assembly. 
     
     
         10 . The system of  claim 1 , further comprising an accommodation tracking module to determine an accommodation of the user's eye, wherein the image injector is configured to input an inverse Fourier transform of a wavefront corresponding to the determined accommodation of the user's eyes.
