摘要： A method and a compact apparatus to read shift-multiplexed holograms on a storage medium without the need for any lenses, and without the need for moving the storage medium. The shift-multiplexed holograms have centers at different locations. The apparatus can generate an array of diverging spherical waves of reference beams, each for illuminating one of the holograms. Each hologram is read as an image on a detector array by illuminating that hologram with a corresponding diverging spherical wave of reference beam. Different holograms can be read by illuminating the medium with a different diverging spherical reference beam. The diverging beams can be from an array of sources, or can be from switching one source.

摘要： An optical information recording/playback apparatus having a compact construction of a recording/playback optical system. A light beam emitted from a laser coupler is modulated by a spatial modulator according to difference in the polarizing direction. The modulated light enters an S-polarized light hologram which separates an information light and a recording reference light of different polarizing directions and having different focal positions. An optical rotation is effected by a split optical rotation plate such that the polarizing directions of the information light and the recording reference light coincide with each other in a region of a holographic layer of a recording medium where the information light and the recording reference light are superposed on each other. The light beam having undergone the optical rotation is applied to the holographic layer through an objective lens, whereby the information carried by the information light is recorded in the holographic layer in terms of an interference pattern produced as a result of an interference between the information light and the recording reference light.

摘要： A one-dimensional data stream is encoded into a two-dimensional data array with reduced high frequency components, for recording on a two-dimensional recording device, such as a holographic storage device. A two-dimensional data array read from the two-dimensional recording device is decoded into the original one-dimensional data stream. To encode, a one-dimensional data stream is partitioned into a plurality of chunks of data. Each chunk of data is partitioned into a plurality of groups of bits. Each group of bits is encoded into a two dimensional data array according to a predefined constraint. A plurality of two-dimensional data arrays are concatenated into a data strip. A plurality of data strips are then assembled into a complete two-dimensional data block. To decode, a two-dimensional data stream is partitioned into multiple small two-dimensional arrays. Each array is decoded into a multi-bit group. In one embodiment, this decoding is a function of other nearby groups. Multi-bit groups are assembled to form a long chunk. Long chunks are assembled to form a one-dimensional data stream.

摘要： Use of an aperture in the reconstructed beam in reconstruction of multiple holograms increases selectivity beyond that realizable by spatial multiplexing so as to permit differentiation of overlapping images. "Aperturization" is suitably used for differentiation in the y-direction in shift holography, depending on Bragg selection in the x-direction.

摘要： Disclosed is a system for the recording of data on optic disks. Presently used optic disks, which can be read with lasers working in wavelengths of the visible region (between 0.5 and 0.8 microns), have a maximum surface storage density of the order of one data bit per elementary zone having an area of about one square micrometer. Beyond this limit, the diffraction does not allow the neighboring zones to be distinguished. A means is proposed to considerably increase the storage capacities: in an elementary zone of a layer, an information bit is written not in the form of a point of absorption of a laser light but in the form of a diffraction grating with a determined pitch. Several diffraction gratings, having pitches different from one another, may be superimposed at the same position, enabling the recording, in one and the same zone, of several information bits. The diffraction gratings are made by a periodic local variation of the optic index of the layer. They are made by a high energy laser beam, out of a material with an index that may vary as a function of this energy. The reading is done by a frequency tunable laser that enables the detection, for different frequencies, of the presence or absence of diffraction gratings.
