| 3989347 | Acousto-optical data input transducer with optical data storage and process for operation thereof The present invention is directed to the improvements in an apparatus for holographically recording data on a storage medium with the data being block-organized holographic data by spatially modulating a laser beam into a plurality of object beams which a... | 11/02/1976 |
| 3987421 | Halographic process for the real-time storage and retrieval of high speed digitally encoded information and an apparatus for implementing said process The process consists in splitting the information into N groups of M bits, in recording the groups on N parallel tracks on the carrier, in the form of M holograms differentiated from each other by the pitch of the interference fringes constituent of each ... | 10/19/1976 |
| 3975081 | Signal recording system An optical recording system for holographically recording one-dimensional information varying with time such as audio signals.... | 08/17/1976 |
| 3970357 | Apparatus for holographic recording Disclosed are a method and apparatus for holographically recording a plurality of holograms on a recording material. The method comprises producing two coherent light beams, altering one of these beams by an information bearing object, causing the changed... | 07/20/1976 |
| 3946430 | Multiple recording system for video signals and optical images A multiplexed holographic recording system employs plural transparent positive pictures, each representing a different pictorial or video information content, which embody differing, unique pre-assigned spatial frequencies. A hologram is formed of the pos... | 03/23/1976 |
| 3936139 | Holographic memory providing both angular and translational reference beam deflections An optical system for the high density storage and retrieving of data, based upon the holographic recording technique, and incorporating two light deviating devices. The first of said devices enables the selection of an elementary area of the storage medi... | 02/03/1976 |
