MULTI-CHANNEL WAVEGUIDE WITH REDUCED CROSSTALK

Last updated:

Abstract:

A waveguide apparatus for conveying a virtual image has first and second parallel planar surfaces. A first in-coupling diffractive optic on the first planar surface directs a first subset of image-bearing light beams into the waveguide and a second in-coupling diffractive optic on second planar surface directs a second subset of the image-bearing light beams into the waveguide. The first and second in-coupling diffractive optics are offset with respect to each other along the first and second parallel planar surfaces to independently direct the respective first and second subsets of the image-bearing light beams into the waveguide.
