Preferably, this holographic version is the nickel version adopting nickel metal plating to copy.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by the reproduction image cycle seamless arrangement of forward and backward scape little light beam, and whole holographic version presents real corrugated space multistory effect.The laser hologram using the utility model to print is undertaken the printing of paper, have mute degree well, third dimension is strong, reproduction image is meticulous, seamless, breadth is large, brightness is high, to advantages such as printing adaptability are strong.
Accompanying drawing explanation
Fig. 1 is that RGB grayscale format instruction figure is as schematic diagram.
Fig. 2 is that the holographic version of the little light beam in a kind of novel large format seamless dumb light space makes schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Composition graphs 1, shown in Fig. 2, the holographic version of the little light beam in novel large format described in the utility model seamless dumb light space, wherein: holographic version has reproducible small embossment lines, some dumb light point holograms that small embossment lines is changed in order by optical diffraction angle, seamless arrangement forms, the angle of diffraction of dumb light point hologram presents order and backward gradual change state respectively along respective width in the two long and narrow unit areas of next-door neighbour, corresponding one group of background and the little light beam reproduction image in prospect dumb light space, some groups little light beam reproduction image in holographic version along the seamless arrangement of unit area width, be full of the holographic version of view picture.
Dumb light point hologram is obtained by the fan-shaped convergent laser bundle of the fillet pointwise exposure in holographic light-sensitive version digital hologram etching system changing in order the anglec of rotation, and the optical diffraction angle of each some hologram is determined by the fillet fan-shaped convergent laser bundle anglec of rotation and be there is one-to-one relationship; The anglec of rotation of convergent laser bundle is determined by grey scale pixel value on the RGB grayscale format instruction figure picture preset and be there is one-to-one relationship; RGB gray value is width work order and the backward gradual change respectively of the two next-door neighbour elongated zones of 8mm at width, the optical diffraction angle creating dumb light point hologram presents order and backward gradual change state respectively along respective width in the two long and narrow unit areas of next-door neighbour, obtains one group of background and the little light beam reproduction image in prospect dumb light space after light reproduces; Some groups of reproduction image along the seamless arrangement of unit area width, are full of the holographic version of view picture in holographic version.
Specifically, as shown in Figure 2, the narrow laser beam 2 produced by laser instrument 1 is by being installed on the optical shaping device 3 on electric rotating machine, produce the fan-shaped divergent laser beam 4 of fillet, the fan-shaped divergent laser beam of fillet 4 is converted to the fan-shaped convergent laser bundle 6 of fillet through imaging len 5, fillet fan-shaped convergent laser bundle 6 converges at the small hole center place of square aperture diaphragm 7 and is full of whole aperture, the fan-shaped convergent laser bundle 10 of fillet is become through imaging len 9 by the fan-shaped divergent laser beam of fillet 8 after the pin-hole filter-ing of square aperture diaphragm 7, and near the latex plane converging at the holographic light-sensitive version 11 be fixed on the two-dimentional precision displacement platform of digital hologram etching system.Meanwhile, the little aperture lens 9 of square aperture diaphragm 7 image in the latex plane of holographic light-sensitive version 11, and exposure obtains a dumb light point hologram.
Digital hologram photoetching control system 13 according to RGB grayscale format instruction figure as the geometric sequence of each pixel on 14 and grey scale pixel value size to laser instrument 1, the electric rotating machine of fixed optics shaping device 3 and the two-dimentional precision displacement platform stepper motor of fixed hologram light sensitive plate 11 send determines instruction: according to the RGB grayscale format instruction figure preset as each grey scale pixel value size on 14, electric rotating machine to fixed optics shaping device 3 sends a corresponding angle command, thus change the anglec of rotation of the fan-shaped divergent laser beam 4 of fillet, finally realize the anglec of rotation of fillet fan-shaped convergent laser bundle 10 and the RGB grayscale format instruction figure one-to-one relationship as each grey scale pixel value on 14, meanwhile, digital hologram photoetching control system 13 sends displacement commands as the pixel geometry sequence on 14 to the two-dimentional precision displacement platform stepper motor of fixed hologram light sensitive plate 11 according to RGB grayscale format instruction figure, realizes by the seamless different-time exposure of pixel.Be of a size of the order gradual change 15 from gray value (1,1,1) to (255,255,255) on the long and narrow unit area of 550mmx8mm, correspondence one is positioned at the little light beam reproduction image of background dumb light below the latex plane of 1 holographic light-sensitive version 1; Be of a size of the backward gradual change 16 from gray value (255,255,255) to (1,1,1) on the long and narrow unit area of 550mmx8mm, correspondence one is positioned at the little light beam reproduction image of prospect dumb light above the latex plane of 11; Order gradual change 15 carries out seamless arrangement with backward gradual change 16 as one-period, by digital hologram photoetching control system 13, the electric rotating machine of laser instrument 1 and fixed optics shaping device 3 and the two-dimentional precision displacement platform of fixed hologram light sensitive plate 11, holographic light-sensitive version 11 realizes the record that breadth is the little light beam hologram in seamless dumb light space of 550mmx416mm.Copy by carrying out nickel metal plating to hologram, the final breadth that obtains is the holographic version of the little light beam in 550mmx416mm seamless dumb light space.
Below the utility model is described in detail, the above, be only the preferred embodiment of the utility model, when not limiting the utility model practical range, namely allly do impartial change according to the application's scope and modify, all should still belong in the utility model covering scope.
