Transparent Waveguide Display
First Claim
1. An apparatus for displaying an image comprising:
- at least one source of image modulated collimated light over an angular range;
at least one waveguide layer comprising gratings for coupling said light into a waveguide path, providing a first direction expansion, a second direction expansion orthogonal to said first expansion and extracting light for viewing from said waveguide, wherein said gratings are configured to provide more than one mode of presentation of data from said source.

Abstract
One embodiment provides an apparatus for displaying an image comprising: a first optical substrate comprising at least one waveguide layer configured to propagate light in a first direction, wherein the at least one waveguide layer of the first optical substrate comprises at least one grating lamina configured to extract the light from the first substrate along the first direction; and a second optical substrate comprising at least one waveguide layer configured to propagate the light in a second direction, wherein the at least one waveguide layer of the second optical substrate comprises at least one grating lamina configured to extract light from the second substrate along the second direction; wherein the at least one grating lamina of at least one of the first and second optical substrates comprises an SBG in a passive mode.
