Abstract: A parity checker is disclosed in which electrical signals representing ''''1'''' and ''''0'''' bits of an information word are supplied to optically aligned electro-optic polarization rotators. A polarized light beam directed through the rotators is rotated 90* an odd or an even number of times depending on whether there are an odd or an even number of 1''s in the information word. An analyzer and a light detector receptive to the rotated beam provides an electrical indication of the parity of the information word.

Abstract: An information storage system including a storage medium comprising a first material characterized by a change in its index of refraction under the influence of an electric field and a different second material characterized by the inducibility of an electric field therein by optical means. The storage medium can be an admixture of two different materials that respectively exhibit these characteristics. Alternatively, the storage medium comprises a plurality of interleaved layers, alternate ones of these layers comprising material exhibiting one of these characteristics and the other layers comprising material exhibiting the second type of characteristic.

Abstract: Information is optically written onto the electrically charged surface of a transparent storage medium by directing light modulated with this information at this surface. The light partially discharges the charge and creates an electrical charge pattern which remains stored for long periods. The light either may be scanned across the surface to achieve sequential information storage or may be employed to write a large amount of information in parallel, for example in the form of a hologram. The stored information may be optically recovered by directing polarized light at the storage medium and employing a suitably oriented analyzer or, in the case of hologram storage, by wavefront reconstruction.
