  • 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.

  • Two stage optical magnification and image correction system
    Publication number: 20010050817
    Abstract: A display having a two-stage optical process is disclosed. This two-stage system enables a relatively compact and inexpensive display. A display screen projects an image that passes through a first lens or lens system. The collimated light is then diffused by one of several methods so as to increase the ultimate viewer's eyebox. The diffused image 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.
