Holography-based Heads-up Display (IMAGE) Optica Caption The new heads-up display uses holographic optical elements to inject an image into the glass, or waveguide (left). The light enters the glass and bounces back and forth between its front and back edges until it reaches another holographic optical element that extracts a small portion of light that leaves the glass with each bounce (right). The extraction holographic creates a viewable image, with each bounce proportionally increasing the eye box size for the image.
