Abstract: A display concept designed to interface with source material from a computer, video recorder or video camera. The interface to a computer generates a series of images that are separate viewpoints of a desired scene to be viewed in three dimensions. The images are based upon a horizontal translation of viewpoints. In the case of a video camera, the interface captures video images from multiple viewpoints and delivers these images in a successive manner to a location at which they can be viewed. The camera requires a single lens and sensor instead of multiple lenses. In the video recorder case, an interface stores images from a computer or video camera and plays back images in the proper sequence for the display. A display system can also operate as a film recorder to provide hard copy, three-dimensional images. A computer, video recorder or video camera thus provides images to a surface which can be viewed and which can present two-dimensional images which are changeable into three-dimensional images.

Abstract: An optical system using a lens assembly with the screen of a computer CRT or LCD unit, said computer being coupled to an electromagnetic radiation source for receiving data therefrom. Data from the source to be presented to the CRT screen is provided as a two-dimensional image rotatable about a selected axis. Light rays from the image pass through the slit of a curtain shutter so that a continuum of views of the image will be projected onto a lenticular film. In another embodiment a Ronchi grating is used. A film having an emulsion engages the back side of the Ronchi grating forwardly of a stationary lenticular screen. A motor drives the Ronchi grating transversely of the light rays. Thus, the rotating image will be represented by light rays which pass to the Ronchi grating. The light rays pass through the grating and expose the emulsion of the film. In the alternative, the Ronchi grating can remain stationary while the film moves relative to the grating.

Abstract: An optical system using a lens assembly with the screen of a computer CRT or LCD unit, said computer being coupled to an MRI apparatus for receiving data therefrom. Data from the MRI to be presented to the CRT screen is provided as a two-dimensional image rotatable about a selected axis.

A motor drives the Ronchi grating transversely of the light rays. Thus, the rotating image will be represented by light rays which pass to the Ronchi grating.

Abstract: A camera having a main lens system designed for normal operation at infinity and well corrected for a flat field. A stationary aperture member having a horizontal slit therein passes light through the main lens system toward and through a lenticular screen which lies ahead of and in close proximity to the sensor plane of a charge controlled device (CCD) chip. The lenticular screen lies flat side toward the imaging plane of the CCD chip and produces a parallax panoramagram of the unidirectional type where only horizontal parallax information is preserved. A portrait lens can be used in front of the main lens system to allow the main lens system to operate at its designed infinity setting. A field lens can be used between the main lens system and the lenticular screen to normalize the light rays from the main lens before they reach the lenticular screen.

Abstract: An improved camera apparatus for three-dimensional photography conventionally includes a stationary frame, a camera body with a film holder for holding photographic film in a film plane and a controllable shutter for exposing film held in the film holder, and a focusable lens assembly attached to the body e.g. by bellows.

Abstract: Apparatus and method of projecting photographic images from a first film onto a second film. The images on the first film are made in a scan camera and represent a series of aspect views of a subject photographed by the scan camera. The apparatus includes means at a first location for mounting the first film adjacent to a first lattice. Light is directed through the first film and the first lattice as the first film and first lattice are moved one pitch line relative to each other. The light is then directed through a projection lens and a second lattice and onto a second film spaced from the first film as the second lattice and the second film move relative to each other one pitch line. The first and second lattices can comprise Ronchi gratings or can be first and second lenticular screens.

Abstract: A method and apparatus for exposing a photographic film with a true three-dimensional image when the image emanates from a photographic film having a pseudo three-dimensional image. A lenticular member having lenticulations on one surface is adapted to be mounted adjacent to a frame containing a film having a pseudoscopic or pseudo three-dimensional image thereon. The frame for the first film is spaced between the flat rear face of the lenticular member and a grating mask having a plurality of uniformly spaced slits therethrough which pass light. A second frame for a second photographic film is mounted on the opposite side of the grating mask. The frames have drive motors coupled thereto and control means causes the drive motors to operate simultaneously to move the frames at the same speed in opposite directions as light enters the lenticular screen and passes through the first film and the grating mask and onto the emulsion of the second film.

Abstract: A method and apparatus for making X-ray photographs which can be viewed in three dimensions with the use of a lenticular screen. The apparatus includes a linear tomograph having a moving X-ray source on one side of a support on which an object is to be placed so that X-rays can pass through the object to the opposite side of the support. A movable cassette on the opposite side of the support moves in a direction opposite to the direction of travel of the X-ray source as the source moves relative to the support. The cassette has an intensifying screen, a grating mask provided with uniformly spaced slots for passing X-rays, a lenticular member adjacent to the mask, and a photographic emulsion adjacent to the opposite side of the lenticular member. The cassette has a power device for moving the lenticular member and the emulsion relative to the mask a distance equal to the spacing between a pair of adjacent slots in the mask.

Abstract: A camera for taking portraits including a main lens designed for normal operation at infinity. The lens has a conventional shutter and an aperture member provided with a slit aperture having a width of about 3.5" and a height of about 0.75". A portrait lens is in front of the main lens to enable the lens to receive parallel light rays representing the image of a subject in a datum plane. A lenticular screen is behind the main lens and defines a film plane at which a photographic film can be placed. A field lens is immediately ahead of the lenticular screen to normalize the converging light rays from the main lens. The lenticular screen has a pitch in the range of 50 to 300 lenticules per linear inch. The lenticules can be vertical or inclined.

Abstract: Lenticular x-ray film having a parallax grating mask near the lenticulations of the film and a high resolution intensifying screen near the emulsion side of the film. The film, the mask and the screen form a unit for placement in a cassette for use with an x-ray tomograph to produce x-ray photographs which can be viewed in three-dimension. The mask has a substrate transparent to x-rays and is provided with spaced recesses for receiving mercury, tungsten or other flowable material which is opaque to x-rays. The spaces between the recesses present gaps for the passage of x-ray beams and the gaps are shaped so that the spread of the x-ray beams striking the emulsion of the film is the same width as each lenticulation. Each groove has a certain height so that the material in the grooves is sufficiently opaque to the x-ray beams in the range of about 30 KVA to about 150 KVA.
