Abstract: This invention teaches a methodology and an optical apparatus that provides long-term, archival storage using a chemically stable, high-resolution, photosensitive emulsion, such as silver halide, for the long-term, archival storage and retrieval of data, images and text. Multiple state data substantially increasing data density is stored as vertical diffraction gratings in the archival photosensitive emulsion. The data can be read out in parallel, substantially increasing retrieval speeds beyond that of current optical and magnetic techniques.

Abstract: The invention combines several techniques applying high-resolution photosensitive emulsions for the long-term, archival storage of data, images and text. Data is stored as vertical interference patterns of multiple frequencies in a photographic emulsion. Read-out of the stored data uses a precision mechanism to locate and decode stored data.

Abstract: The invention relates to imaging devices and methods, pertinent to electromagnetic energy in visual and other spectra, to capture and reproduce substantially all image information in a relevant spectrum through all-electronic sensors and electronic computation means.

Abstract: The present invention relates to sensor apparatus and methods, pertinent to electromagnetic energy in visible and other spectra, to capture and reproduce substantially all electromagnetic information within a relevant spectrum. This invention takes advantage of the wave properties of light, using tiny components dimensioned to the relevant wavelengths of light. Recent developments in nano-technology permit construction of wave-based detectors, instead of photon-counting receivers. These wave detectors can operate in the electromagnetic spectral range, including submillimeter, infrared, visible, ultraviolet and X-ray bands, with consequent low noise and tremendous sensitivity due to gain resulting from their inherent antenna construction. This invention provides for both non-contact and contact coupling methods between the sensor and the receiver/demodulator.

Abstract: This invention teaches how to fabricate a new type of full-spectra wavelength detector and spectrum analyzer in the form of antennas that make use of the wave properties of light. The detector's frequency detection range is controlled through the fabrication process. By miniaturizing the antenna detectors to the nanometer range and arranging them in an array a unique, full-spectrum imaging sensor is created.
