Definitions

  • This invention relates to the process of holography. It is devoted to a method of contact copying of holograms and holographic prints, using pulsed or continuous wave (CW) lasers. This invention may also be used to produce Denysiuk type holograms of relief objects e.g. coins, paintings etc.
  • CW continuous wave
  • a known method of contact copying holograms is described in USA patent No. 4416540.
  • the non-exposed light sensitive material is applied on a base and is positioned in parallel to the plane of the master hologram (on or beyond it). This is then illuminated with a narrow slit shape beam of coherent laser light radiation.
  • the coherent laser radiation reconstructs the information recorded on the master hologram, i.e. becomes the object beam and the reference beam simultaneously exposing the previously non-exposed light sensitive material.
  • the data stored in the master hologram is recorded on the previously non-exposed light sensitive material.
  • the zone of the master hologram illuminated by the slit shaped laser beam is perpendicular to the projection of the coherent light directed toward the surface of the master hologram.
  • the slit zone is transported on the surface of the non-exposed light sensitive material in the direction that is parallel to the said projection of the coherent light falling direction onto the master hologram surface.
  • This zone of the parasitic lighting increases as the distance between the master hologram and the non-exposed light sensitive material diverges and as shaper becomes an angle of incidence of coherent light beam during the contact copying. Since the master hologram per se is usually recorded on the light sensitive material and is placed on the same base, the gap between the master hologram and non-exposed ligh sensitive material always exists, and the angle of coherent light beam incidence might reach 15-20°.
  • the purpose of proposed invention is to improve the copying quality of the holograms and holographic prints and to enable the production of Denysiuk type holographic records of the relief objects (coins, paintings etc.).
  • non-exposed light sensitive material applied on a base and positioned in parallel to the plane of the master hologram or the holographic print is illuminated by a slit-shaped beam of coherent laser radiation in such a way that the previously non-exposed zone, illuminated by this beam, is parallel to the projection of the coherent light falling direction onto the plane of master hologram or the holographic print, and this zone is transported on the surface of non-exposed light sensitive material and on the surface of master hologram or holographic print in the direction, which is perpendicular to the projection of the coherent light beam (which illuminates hologram or holographic print and reconstructs its image information) falling direction onto the surface planes of the materials mentioned.
  • the length of the zone illuminated by the narrow slit-shaped laser radiation beam, at the location where this beam falls onto the light sensitive material is at least 1% longer than the length of the master hologram and the length of the non-exposed light sensitive material.
  • the laser radiation beam optionally has a shape of narrow oblong rectangular or the elongated oval.
  • the laser radiation might optionally be pulsed, and the radiation energies distribution might optionally have Fl shape.
  • illumination of material to be copied might be performed by multiple colours coherent radiations simultaneously.
  • illumination of material to be copied might be performed by different colour coherent radiations successively.
  • the proposed method is helpful in improving the copying quality of the holograms and holographic prints and allows holographic copying of the relief objects (coins, paintings etc.) producing Denysiuk type holograms.
  • Fig.1 shows the scheme of the proposed hologram copying method (side view);
  • Fig. 2 shows the scheme of the proposed hologram copying method (front view);
  • Fig. 3 shows the scheme of the proposed hologram copying apparatus.
  • the proposed method comprises following steps:
  • the zone 5 illuminated by slit-shaped coherent laser radiation beam is parallel to the lighting direction 6 projection onto the plane of the master hologram 3 surface; - the lighting direction 6 is chosen in such a way that maximum brightness of the reconstructed image of the master hologram would be perpendicular to the master hologram plane; - the zone 5 illuminated by the slit-shaped coherent laser radiation on the master hologram is at least 1% longer than the length of the master hologram or holographic print 3 and the length 9 of the non-exposed light sensitive material 1 ; - the zone 5 enforced to move continuously in the direction 10, which is perpendicular to the projection of the coherent light falling direction 6 onto the plane of the master hologram or holographic print 3.
  • pulsed lasers 11 are employed as the coherent radiation sources. These lasers have three different wavelengths: in the range of red, green and blue color spectrum.
  • a beam formation/deflection system 18 which has the device for the beam shaping into the form of narrow oblong rectangular or elongated oval slits 19. Shaping/deflection system 18 is fixed on the computer controlled translation motion mover 20. This mover is able to move to the direction 21.
  • the beam, formed with shaping/deflection system 18, falls onto the mirror 22, which is placed in such a way, that the beam reflected by the mirror 22, would fall onto the non-exposed transparent light sensitive material 1 in the direction 6, to obtain illuminated zone 5 parallel with the lighting direction 6 of the master hologram 3, and seeking to reproduce the master hologram image in such a way that the maximum brightness of this image would be perpendicular to the plane of the master hologram 3 surface.
  • the width 23 of the mirror 22 is chosen in such a way, that the zone 5, obtained by reflecting the coherent radiation beam from said mirror, would illuminate the desirable area of the master hologram 3 by moving this beam with the mover 20 of translation motion. At the same time the beam of the coherent radiation exposes needed area of the non-exposed light sensitive material 1.
  • the length 24 of the mirror 22 is chosen in such a way, that the length of illuminated zone 5, obtained by reflecting the coherent radiation beam from said mirror, would be at least 1% longer than the length of the master hologram 3 and the length 9 of the non exposed light sensitive material 1.
  • the method is to be implemented in following way.
  • the wavelength of the each of the radiations generated by lasers 11 has to match wavelengths of the spatial image formed by the coloured (or monocolor) master hologram or holographic print 3.
  • the computer-controlled wave plates 12 and polarizers 13 adjust colour balance.
  • the laser 11 beams then are deterged with the telescopic laser beam cleaners - spatial filters 14.
  • the polarization correctors 15 compensate spatial filters 14 polarization.
  • the beams by the mirrors 16 are directed to the three-colour combiner- deflector 17.
  • the beams from the combiner-deflector 17 are heading the same direction and way, directed to the laser radiation beam shaping/deflection system 18.
  • This system forms laser radiation beam into shape of the narrow oblong rectangular (or the elongated oval) slit 19. Then beam, reflected by flat or other form mirror 22, falls onto the non-exposed light sensitive material 1 and onto the master hologram or holographic print 3.
  • the width 23 of the mirror 22 is chosen in such a way, that coherent radiation beam reflected by it formed the illuminated zone 5, which would illuminate the necessary area of the master hologram or holographic print 3 and would expose the necessary area of the non exposed light sensitive material 1 by moving this zone 5 with the translation motion mover 20.
  • the length 24 of the mirror 22 is chosen in such a way, that the length of zone 5 illuminated by coherent radiation beam reflected by said mirror, would be at least 1% longer than the length of the master hologram or holographic print 3 and the length 9 of the non exposed light sensitive material 1.
  • the slit-shaped laser radiation falls onto the non-exposed light sensitive material 1 , which is coated on the flexible or solid flat base and is placed on or beyond the master hologram or holographic print 3 to be copied.
  • the laser radiation beam 5 is going in direction 6 in such a way, that the illuminated zone 5 would be parallel to the projection of the master hologram or holographic print 3 illuminating direction 6 to the master hologram 3 plane.
  • the laser radiation shaping/deflection system 18 is fixed on the computer controlled translation motion mover 20, which assures its even movement in direction 21.
  • the translation motion mover 20 assures the coherent light radiation movement in direction 10, which is perpendicular to the projection of the coherent lighting beam that illuminates the master hologram, falling direction 6 to the master hologram plane. This assures the even exposure of non-exposed light sensitive material and master hologram, causing the even recording of reconstructed master hologram data.
  • the proposed method is helpful in improving the copying quality of the holograms and holographic prints and allows holographic copying of the relief objects (coins, paintings etc.) producing Denysiuk type holograms.
