    摘要: According to one aspect and example, a holographic recording system includes a light source, an object for modulating an object beam from the light source, and a relay system adapted to magnify (positive or negative) the modulated beam (e.g., an image of the object) to an output image. The object may include an SLM operable to modulate the object beam with an information layer comprising a plurality of data pages. The output image is directed to the holographic storage medium, where a reference beam is also directed, to record the resulting interference pattern. Additionally, the relay system converges the output image to an output Fourier plane, which may be disposed within the holographic storage medium. A filter may be placed at an intermediate Fourier plane located prior to the output Fourier plane, and a phase mask may be placed at the position of the output image.

    摘要: According to one aspect, methods and systems for recording and reading holographic storage media are provided. In one aspect, a method includes illuminating a data mask with a beam and recording a resulting modulated beam in a holographic storage medium, wherein the data mask includes an information layer that is divided into multiple data pages, and propagating a reference beam to the holographic storage medium to record the multiple data pages of the data mask in a parallel fashion on the holographic storage medium.

    摘要: Systems and methods for processing content packages such as human-readable documents identify and analyze content type. Structural and logical evaluation of a content package is performed, followed by analysis and indexing of concepts within the package. Analysis and identification of concepts and sub-concepts may be an iterative process. Concepts are indexed in accordance with different rule sets representing different consumer needs and perspectives. Customers can then use the indices to navigate large groups of content packages based on the concepts contained within those packages and also on keywords associated with concepts.

    摘要: Associative retrieval techniques of this invention allow a holographic recording device to simultaneously query a plurality of storage locations for the presence of a given data pattern. The techniques use a known pattern common to one or more storage locations to simultaneously verify the success of one or more write operations.
