  • Three dimensional projection arrangement
    Patent number: 4571041
    Abstract: A projection arrangement for projecting three-dimensional images of objects into space. The object is illuminated by a source of light, and the light rays reflected from the object are directed so as to be incident on a mirror surface located behind a lens. The mirror surface receives an image from the lens and the combination forms an enlarged three-dimensional image projected into space. The lens can be in the form of a modified Fresnel lens of multiple focal lengths and having spherical zones in the form of strips. The Fresnel lens, which may be used in combination with other optical elements, provides a substantially large field of view suitable for viewing a three-dimensional image of the object by a mass audience. The image projection may be achieved without the use of a screen. The enlarged three-dimensional image appears floating in space visible to unaided eyes of an audience.
