Image projection may be facilitated by a layered waveguide and/or other components. The layered waveguide may have an input portion and a presentation portion. Light may be received from a display at the input portion and output at the presentation portion. Th input portion may include coupling optical features. The presentation portion ma include presentation optical features forming Bragg diffraction gratings. Relative proportions of light emitted by the display and coupled onto the layers may be controlled adjust a cumulative focal length of the layered waveguide."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection systems and methods","description":"Systems and methods of image projection are presented herein.
