    摘要： This invention concerns a luminescent optical memory material and method of forming this material, including the encoding of information by a photographic process. The method involves the use of silver halide crystals of a defined size range, with the optional use of sensitizers, emulsion stabilizers, and other agents followed by the absorption of luminescent dyes on the developed silver particle to form a luminescent optical memory system. The method involves synthesis of a photographic emulsion with silver halide crystals of a defined size range, applying photographic emulsion to a substrate, exposing to light photochemical treatment and a process of transformation of the silver particles formed in the places exposed by light into luminescent particles. The method involves obtaining a multi-layer luminescent material for a three-dimensional optical memory devices.

    摘要： An optical pickup providing the 3-D reading of the binary optical information from the multilayer fluorescent disk by means of fluorescent sites excitation, is described. The 2-D information at the separate layer is recorded by chemical transformation of the photosensitive material from one stable molecular form A (non fluorescent) to other stable molecular form B (fluorescent) via UV light illumination.The present invention particularly concerns the methods and apparatus to read the stored memory from the read only 3-D optical memory and includes: (i) only one, focused to the desired layer, reading laser beam, which induces the fluorescence in the whole volume confined within conical surface of focused beam, (ii) active medium which posses the fluorescing properties and is organized in a form of multilayer optical disc, (iii) detection of fluorescence at the wavelength different from the excitation wavelength, (iv) spectral, spatial and electronic filtration of the detected signal in order to extract signal from the noise fluorescence coming from all out-of-focus layers. Utilization of dichroic mirror and/or filter in the optical pickup prevents the photo diode from the reading laser radiation.
