Abstract
A head mounted display system is shown having a single optical element. The single optical element has three optical surfaces. An entrance surface receives a video image directly from a display. A reflective surface reflects the video image from the entrance surface to an exit surface wherein the user views the video image directly through the exit surface. The three optical surfaces are shaped to generate a virtual image that is magnified, appears at a distance from the user and substantially free from distortion, astigmatism and chromatic aberrations. The optical element is adjustably mounted on a frame of the head up display system to accommodate users with different interpupillary distances and to vary the apparent distance between the user and virtual image.
