    Abstract: A coordinate input device having two beams of pulsed laser light passing through a photochromic glass plate. The successive intersection points of pulses from the two beams scan the plate along a raster to successively mark each coordinate position on the plate. A light pen directs ultraviolet light onto the surface of the plate to generate a scattering center at any chosen coordinate on the plate. Laser light is scattered by such centers and is detected by the light pen. The greater amount of light scattered at an intersection point is used to generate an indication of the chosen coordinate. Another embodiment uses roughened glass, rather than photochromic glass, to cause scattering.

    Abstract: 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 scan which is at an angle of about 45 degrees with respect to the plane of rotation of the cylinder. The azimuthal position of the line scan can be varied by the rotation of a small mirror which directs the illumination beam. As a consequence, a two-dimensional raster scan on a cylindrical image surface is produced.

    Abstract: NON-DESTRUCTIVE READOUT SCHEME FOR HOLOGRAPHIC STORAGE SYSTEM of the Invention A non-destructive readout scheme suitable for use with a holographic storage system having data stored in three spatial dimensions and one frequency dimension is described. The readout scheme and the holographic storage system use a preferred storage material which undergoes a reversible photochromic reaction involving two inhomogeneously broadened absorption bands. Information is written into the storage system by exposing the material to a holographic interference pattern of light at a frequency within either one of the two absorption bands. The non-destructive readout scheme involves reconstructing the original information by sensing the change in the index of refraction at a frequency just outside of and near either one of the two absorption bands. The readout scheme also includes sensing refractive index changes near one or more narrow absorption lines within either absorption band.

    Abstract: HOLOGRAPHIC OPAQUE DOCUMENT SCANNER An opaque document scanner in which a moving hologram generates a locus of points from a stationary light beam on an opaque document and the same hologram or a similar one mounted for conjoint movement collects light energy reflected from the document at each point and focuses this energy onto a stationary detector to provide electrical signals corresponding to the information scanned on the document.
