  • Stereoscopic video/film adapter
    Patent number: 6683716
    Abstract: A method for creating stereoscopic images wherein an image altering filter is interposed at the aperture stop of a relay lens system. The relay lens system forms an adapter between the ocular hole of an instrument and the oculars of an instrument. When a pair of such adapters are used in a binocular instrument, and when the adapters are correctly oriented, a 3D image is made available for viewing.

  • Stereoscopic telescope with camera
    Patent number: 6546208
    Abstract: The optical device of the present invention is able to capture a three-dimensional image via one or more imaging devices while permitting the viewer to view the object(s) during image acquisition. The user is thereby able to adjust the orientation of the optical device to obtain the desired image.

  • Single-lens 3D method, microscope, and video adapter
    Publication number: 20010040724
    Abstract: A method and teaching for creating stereographic images with the use of a single lens is presented. A leading linear polarizing filter, a passive half-wave retarder, an electric switched quarter-wave retarder, and a trailing linear polarizing filter are then used in various combination to create: a 3D microscope, a 3D video adapter for microscopes, a general purpose 3D video lens, a 3D video adapter, and a 3D light-valve. A neutral density filter replaces those components to then create a 3D ocular and a 3D ocular adapter.
