GENERATING A LIGHTFIELD USING A PLURALITY OF SPATIAL LIGHT MODULATORS
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.
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 first spatial light modulator (SLM) configured to selectively transmit light rays associated with the one or more frames of image data;
a second SLM positioned in relation to the first SLM, the second SLM also configured to selectively transmit light rays associated with the one or more frames of image data; and
a processor to control the first and second SLMs in a manner such that a lightfield is created when the transmitted light rays are viewed by the user.
2 . The system of claim 1 , further comprising an accommodation tracking module to determine an accommodation of the user's eyes.
3 . The system of claim 1 , wherein the SLM is an LCD.
4 . The system of claim 3 , wherein the LCD is attenuated.
5 . The system of claim 3 , wherein the LCD rotates a polarization of the transmitted light.
6 . The system of claim 1 , wherein the SLM is a DMD.
7 . The system of claim 6 , wherein the DMD is coupled to one or more lenses.
8 . The system of claim 1 , wherein the SLM is a MEMs array.
9 . The system of claim 8 , wherein the MEMs array comprises an array of sliding MEMs shutters.
10 . The system of claim 8 , wherein the MEMs array is a Pixtronics® MEMs array.
