Abstract: A waveguide structure for a head up display in which a reflective output coupling structure is formed of a separate, but connected, component to a main waveguide. In a method of manufacture for such a waveguide the output coupling structure may be formed by depositing a material on a main waveguide, impressing the reflective structure into that material, and curing the material.

Abstract: A waveguide structure for a head up display in which a reflective output coupling structure is formed of a separate, but connected, component to a main waveguide. Light is coupled from the main waveguide to the output coupling structure by evanescent wave coupling. In a method of manufacture for such a waveguide the output coupling structure is attached to the main waveguide using an optical feedback technique.

Abstract: A method is provided for adjusting a luminance profile of an image displayed on a look-through display to a user. The method comprises: determining a field of view of the user based on a spatial configuration of the user's head. Determining one or more lighting conditions in the field of view. Adjusting the luminance profile for the image based on the field of view, wherein, as a result of the adjusted luminance profile, the image is reconciled with the field of view.
