| Number | Title | Issue Date |
| 4566031 | Spatial light modulation with application to electronically generated holography A spatial light modulator with application to holography utilizes two planar transparent supports between which is positioned an electro-optical dipolar medium which is normally opaque but light transmissive in the presence of an applied electric field. O... | 01/21/1986 |
| 4532422 | Electron holography microscope The present invention provides an electron holography microscope producing an interference pattern having contour moire lines which is displayed on a cathode-ray tube. With the invention the three-dimensional structure of a specimen can be readily observe... | 07/30/1985 |
| 4520387 | Holographic imager A holographic apparatus uses electronically processed three-dimensional information about an object to produce a three-dimensional display of that object and its movement. A holographic screen has a plurality of angularly multiplexed holographic images wh... | 05/28/1985 |
| 4484219 | Electronically generated holography Holographic data in the form of electronic signals is generated through the utilization of two planar transparent supports between which is positioned an electro-optical dipolar medium which is normally opaque but light transmissive in the presence of an ... | 11/20/1984 |
| 4376950 | Three-dimensional television system using holographic techniques A hologram, produced by illuminating an object via a coherent light source and associated optics, or by digital components or photographic components, is imaged onto, for example, a television camera to selectively provide either a real time, or a non-rea... | 03/15/1983 |
| 4359758 | Holographic television A holographic television system is disclosed which is capable of generating, transmitting and reconstructing three-dimensional moving pictures in real time and in color while using no more electromagnetic bandwidth for transmission than required by presen... | 11/16/1982 |
| 4282295 | Element for thermoplastic recording In a thermoplastic-photoconductor holographic recording medium in the form of several transparent layers over a transparent substrate, such as an optically transparent electrically conductive layer, then a photoconductor layer and a thermoplastic layer ov... | 08/04/1981 |
| 4229761 | Illusion transmitter A real time illusion transmitter for transmitting three dimensional illusions of an object comprising a first parabolic mirror for producing a real image of an illuminated object, image detection means disposed in a position to receive said real image and... | 10/21/1980 |
| 4195221 | Scanning focused local oscillator optical heterodyne imaging system In an optical heterodyne system a first coherent light signal is received on an ordered array of light responsive elements, and a local oscillator source provides a second coherent light signal, the frequencies of the first and second coherent light signa... | 03/25/1980 |
| 4148636 | Broadening the spatial frequency pass band of a thermoplastic layer A layer of thermally deformable plastic used, for example, in a holographic recording medium has an undulated surface whereby the layer has an uneven thickness. Because of the uneven thickness, the layer has a composite spatial frequency pass band greater... | 04/10/1979 |
| 4137077 | Broadening the spatial frequency pass band of a thermoplastic layer A layer of thermally deformable plastic used, for example, in a holographic recording medium has an undulated surface whereby the layer has an uneven thickness. Because of the uneven thickness, the layer has a composite spatial frequency pass band greater... | 01/30/1979 |
| 4076372 | Two-dimensional light deflector apparatus A two-dimensional light deflector is shown which comprises a cylindrical member having a plurality of holograms recorded thereon. A collimated light beam is directed to illuminate the hologram cylinder and rotation of the hologram cylinder provides a line... | 02/28/1978 |
| 4034355 | Holographic digital data processing system with sequential data storage and retrieval A holographic digital data processing system is described in which the data is stored holographically in a recording medium with the data insertable and retrievable in a sequential manner. A modulated data beam and a similarly modulated reference beam are... | 07/05/1977 |
| 3947630 | Imaging devices Optical diodes are shown in the forms of a mechanically contacted cat whisker system and as single and multiple microscopic solid portions in an integrated solid mass, defining both the antenna and the junction, preferably as a deposit of solid layers upo... | 03/30/1976 |
