Abstract
The head up display provides light from an image source. The head up display includes a waveguide assembly comprising a first waveguide for disposition at an angle with respect to a top surface of a glare shield and a second waveguide disposed at an angle with respect to the first waveguide. The first waveguide has a first diffractive coupler at a first end and a second waveguide has a second diffractive coupler at a second end. The first waveguide is positioned as a combiner and allows viewing of an outside scene and information from the image source. At least part of the first waveguide is disposed beneath the top surface of a glare shield.
