  • Two stage optical system for head mounted display
    Patent number: 6417970
    Abstract: A head-mounted display having a two-stage optical process is disclosed. This two-stage system enables a relatively compact and inexpensive head mounted display. The head-mounted display has two sections extending rearward around the sides of the head. Within each section, a display screen projects an image that passes through a first lens. It then undergoes a magnification process involving total internal reflection within a second lens. The light exiting the second lens is magnified to the level desired at a low cost and a small size.
