    摘要: An apparatus for providing an optical display includes an optical substrate for propagating light received from a light source, a first set of one or more switchable diffractive elements in the substrate, and a second set of one or more switchable diffractive elements in the substrate. Each diffractive element in the second set corresponds to a diffractive element in the first set. Each of the diffractive elements in the first and second sets is configured to switch between on and off states. One of the states is for diffracting light and the other state for allowing light to pass through. Each of the first set of diffractive elements is configured to diffract the light at an angle for propagation in the substrate. Each of the second set of diffractive elements is configured to diffract the light for display.

    摘要: 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.
