Abstract: A holographic mirror is made by a process of continuous exposure. For this purpose, a photosensitive layer (10) is exposed strip by strip in a direction crosswise to that in which the layer is exposed by two interfering beams (6, 6'). Film (11) bearing photosensitive layer (10) is continuously moved in the longitudinal direction (F) at a speed that ensures sufficient exposure of the layer. The procedure makes it possible to produce holograms of any length in one direction.

Abstract: A three-step process is combined with an edge-lit system to provide a self-contained, maximally-compact holographic display. In one embodiment, a hologram is affixed to an upstanding transparent support plate mounted through the top of a housing in which the hologram is edge-illuminated with white light from a source in the housing immediately beneath the plate to generate brilliant, sharp and deep multi-color images which straddle the hologram plane. In another embodiment, the transparent support plate is mounted in a frame which carries the edge-illumination source. All displays may either be free-standing or wall-mounted, as desired.

Abstract: Highlighting a selected area of a holographic display indirectly by selectively repositioning a small lens within the hologram illumination beam.

Abstract: An apparatus for interfacing holographic and electronic data comprises an input/output port for the interfacing of a holographic wavefront interference pattern and an electronic array capable of producing digital electronic information from a holographic wavefront input and for converting electronic information into holographic information using optical fibers, sensors, and optical switches. In one embodiment a plurality of optical fibers having a small end and a large tapered end are operably combined with a plurality of optical sensors wherein each of said optical sensors provide a digital signal of 1 if lit and a digital signal of 0 if unlit.

Abstract: A holographic television apparatus is disclosed for detecting and displaying three-dimensional holographic information corresponding to a holographic optical interference pattern. The apparatus includes an image detecting device for successively detecting two-dimensional slices of the three-dimensional holographic optical interference pattern, an image reproduction device for successively reproducing two-dimensional slices of the three-dimensional holographic optical interference pattern, a transmission means connecting the image detection device to the image reproduction device, and an actuation unit for moving the image detection device at predetermined regular intervals in an depth direction normal to the two-dimensional image portions to obtain information with respect to the three-dimensional optical interference pattern at unformly spaced two-dimensional layers thereof corresponding to the displacement intervals.
