ホログラムを複製するものである。As described above, when color holograms are copied from the original holograms of R, G, and B colors to the same photosensitive material for duplication, in order to make the reproduction light angles of the duplicates the same for all three colors, close contact is required. Change the degree of swelling of the photosensitive material for duplication,
The original hologram must be exchanged and the angle of reproduction light must be changed to irradiate. In the present invention, as shown in FIG. 1, an original hologram reproduced by reproduction light of the same wavelength, wherein the incident angles θ R , θ G , and θ B of the reproduction light are different for each of the colors R, G, and B. The original holograms 1 R , 1 G , and 1 B are prepared, and these original holograms are attached to the same drum 5 while exchanging them as shown in FIG. Then, laser beam 8 for reproduction, which is a laser beam that travels in parallel with a predetermined plane 7 including the axis 6 of the drum 5 and whose cross section is a line parallel to the axis 6 of the drum, is attached to the drum 5. The original holograms 1 R , 1 G , and 1 B attached are arranged so as to be irradiated. At this time, if the distance D between the predetermined plane 7 and the reproduction laser linear light 8 is changed, the incident angle θ of the reproduction light 8 to the original hologram changes. Therefore, in the present invention, the distance D is changed according to the exchange of the original hologram, and the incident angle of the reproduction light 8 is selected from among θ R , θ G , and θ B. 5, a wavefront is reproduced from each portion of the original hologram, and an interference fringe between the wavefront and the reproduced light 8 is brought into close contact with the original hologram and travels at the same speed as this. ) And duplicate the original hologram.

グラムからホログラムを複製するにもできる。In the above, the method and apparatus for replicating a reflection hologram of the present invention have been described with respect to an example of producing a color hologram from three hologram masters. However, the present invention is not limited to this embodiment, Deformation is possible. For example, from an original reflection type hologram that is multiplex-recorded while changing the incident angle of the reference light, the hologram can be similarly copied. Further, one multiple recording hologram can be similarly formed from a plurality of original reflection holograms separately recorded by changing the incident angle of the reference light. Further, as a matter of course, a hologram can be copied from one original reflection hologram.

くらべ作業能率が大幅に向上する。According to the present invention, a large number of original reflection holograms can be easily produced simply by attaching the original reflection hologram to a rotatable drum and irradiating a reproduction light having a linear cross section parallel to the axis of the drum. Can be duplicated. Further, by simply changing the position of the reproduction light up and down, the angle of the reproduction light incident on the original reflection type hologram can be changed. According to this method and apparatus, a desired angle can be obtained without reassembling the optical system by first obtaining the amount of change in the vertical movement of the laser linear light and the resulting change in the angle of the illumination light. Work efficiency is greatly improved.
