Title:
円偏光子を備えた画像光ガイド
Document Type and Number:
Japanese Patent JP6956887
Kind Code:
B2
Abstract:
An imaging apparatus for conveying a virtual image superimposed within a view of an ambient environment has a waveguide having first and second surfaces. An in-coupling diffractive optic on one of the planar surfaces is disposed to direct image-bearing light beams into the waveguide. An out-coupling diffractive optic on one of the planar surfaces of the waveguide is disposed to direct the image-bearing light beams from the waveguide toward a viewer eyebox. An outer cover protects as least part of the waveguide from undesirable environmental influences of an ambient environment while supporting views of the ambient environment from the eyebox. A circular polarizer interposed between waveguide and the outer cover blocks the return of stray light into the waveguide.
