Abstract: The method involves growing a boule of co-doped LYSO:Ce,Ca scintillation crystal containing Ce3+ ions and Ce4+ ions in a ratio of about 1:1, wherein the grown boule is substantially free of Li+ ions and Mg2+ ions. This is achieved by providing a specialized crystal growing device having an inner iridium crucible and loading it with specific oxides and a carbonate salt in specific amounts. The loaded iridium crucible is then subjected to a vacuum and then pressurized with a specific gas mixture consisting mostly of Ar admixed with a small amount of CO. The loaded and pressurized iridium crucible is then heated to yield a melt, into which a seed crystal is placed to grow (by way of the Czochrolaski pull method) an unfinished crystalline boule. This unfinished boule is then annealed in the same special pressurized atmosphere to yield the final boule of co-doped LYSO:Ce, Ca scintillation crystal.

Abstract: This invention relates to optical-electronic technology and can be used for building 3-dimensional displays for computers, television (TV) receivers and other devices, as well as for building systems for volumetric television. The technical result is an increase in the number of aspect angles with relatively simple construction and the use of presently available components. The equipment generates a 3-dimensional representation and contains a display component for 2-dimensional representation with digital inputs and a first 2-dimensional matrix of converging micro-lenses, in which each micro-lens is optically joined to the corresponding region of the display surface of the component for display of 2-dimensional representations.

Abstract: The invention provides methods and apparatuses for vision therapy procedures using laser interference patterns for relieving eye strain. One of the methods provided controls a speckle pattern in such a manner that an interesting visual stimulus is created which attracts and retains a viewer's attention and forces the eye to adjust to distance vision. This stimulates relaxation of the ciliary muscles of the viewer's eyes and contributes to the relief of eye strain. Another method provides electronically generated holograms for exercising eye muscles in order to relieve eye strain. The present invention provides further methods and apparatuses which may be used in a computer user's workplace.
