ABSTRACT:
A head up display system for a vehicle includes an image source and an optical combiner which reflects the projected image from the image source toward an observer for observation. The optical combiner is positioned so that the observer, in a line of sight, sees both a visual exterior view of an outside scene through the combiner and the projected image in the combiner. In disclosed embodiments, the optical combiner comprises wedge lenses.
