Using a plurality of optical fibers for augmented or virtual reality display
First Claim
1. A system for displaying virtual content to a user, comprising:
- a plurality of optical fibers to project light associated with one or more frames of image data to be presented to the user,a lens coupled to an exit end of an optical fiber of the plurality of optical fibers;
an actuator coupled to the lens to scan the lens;
a first reflector to reflect transmitted light associated with a first frame of the one or more frames of image data at a first angle to an eye of the user; and
a second reflector to reflect transmitted light associated with a second frame of the one or more frames of image data at a second angle to the eye of the user, wherethe first reflector and the second reflector are configured such that a respective refractive index is varied in an analog manner based in part or in whole upon a total number of sub-frames in the first frame or the second frame as well as a refresh rate at which the one or more frames are presented to the eye of the user,wherein the lens is configured to alter a diameter of a light beam projected by at least one of the plurality of optical fibers,wherein the lens comprises a gradient refractive index, andwherein the actuator is configured to cause scanning of the lens separately from causing scanning of the at least one of the plurality of optical fibers.

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.
