ある。In the figure, a cylindrical original drum 4 is used, a reflective hologram original 5 is pasted thereon, a photosensitive material film 6 for duplication is wound around this drum, and the drum and film are rotated at the same speed. By irradiating the laser beam 7 from the material film side, the reflected light and the irradiated light are caused to interfere, and the interference fringes are recorded on the film, thereby making it possible to create a hologram. In this way, by pasting the original onto the entire drum cylinder and supplying the film one after another, production efficiency can be greatly improved compared to conventional duplication methods, making it possible to perform mass production. This is a diagram showing a configuration for mass-duplicating holograms by the duplication method shown in FIG. 1, in which 8 is a reflective hologram original plate, 9 is an original pasting drum, 10 is a laser oscillator, and 11 is a film unwinding device. , 12 is a film winding device, 13 is an index matching liquid dropping device, 14 is a nip roller, l5 is a drying device, l6 is a cylindrical lens, 17

用できる。As is generally known, the interval between interferences. d1 wavelength is λ, refractive index is n, and the nucleus formed by the object light and reference light is θ
Then, it becomes λ. Therefore, the factor that determines the reproduced color of a ribbon man hologram is the interval between the interference fringes formed in the photosensitive material; by increasing this interval, the reproduced color shifts to longer wavelengths, and by decreasing the interval, the reproduced color shifts to longer wavelengths. Shift to shorter wavelengths. Therefore, as shown in FIG. 3(a), after the photosensitive material is swollen, dried, and exposed, the swelling is released and the material is shrunk.
By developing, the interval between interference fringes can be reduced, and the reproduced color can be shifted to shorter wavelengths. The amount of shift at this time is when the photosensitive material is immersed in a D-sorbitol aqueous solution for 1 minute and then dried, which is a swelling process, and then exposed to He-Ne laser light (63.31 m) and developed. The characteristics are as shown in FIG. 3 (mouth). That is, when the concentration of the D-1 rubitol aqueous solution is 0%, it is red, when the concentration is 5%, it is orange, when the concentration is 6 to 7%, it is yellow, when the concentration is 10%, it is yellow-green, and when the concentration is 14%, the edge, the concentration When the concentration is 20%, the color is blue, and when the concentration is 30%, the color is purple. So R
When photographing from a holographic stereodulum, it is preferable to perform exposure after processing with a D-sorbitol aqueous solution with a density of 0%, G and B at a concentration of about 10% and 20%, respectively. In addition to the D-sorbitol aqueous solution, various saccharide aqueous solutions such as a triethanolamine aqueous solution and a maltose aqueous solution can be used as the swelling treatment liquid.
このようにして、感光材料に膨潤処理を施した後露光を
行う工程をＲ，Ｇ，Ｂの３回行った後、適当な現像処方
に従って現像処理を行うことによってナチュラル力ラー
リップマンホログラムが得られる。In this way, after performing the swelling treatment on the photosensitive material and then exposing it to light three times for R, G, and B, a natural Rarippmann hologram can be obtained by performing development according to an appropriate development recipe. .
なお、Ｈｅ−Ｎｅレーザーに代え、例えば八「レーザを
用いた場合には、現像後膨潤処理を行って長波長側ヘシ
フトするようにすればよい。但し、この場合は膨潤剤が
残存することになる。If, for example, an 8-inch laser is used instead of the He-Ne laser, a swelling treatment may be performed after development to shift the wavelength to the longer wavelength side.However, in this case, the swelling agent may remain. Become.
以上の原理を応用してカラーホログラムの複製が可能で
ある。It is possible to reproduce color holograms by applying the above principles.

ので、多色のパートカラーホログラムが得られる。For example, when a silver salt material is used as a photosensitive material film for duplication, a swelling liquid is applied to the surface of the photosensitive material film before exposure to swell the sensitizer, and by exposure and development to release the swelling, the wavelength of the laser beam can be lowered. It is possible to obtain a replica with a reproduction light of . That is, multiple sets of the exposure process shown in Fig. 2 plus a swelling treatment process are arranged in series, and in each set of processes, a different original plate is pasted on the original plate pasting drum to change the degree of swelling, thereby reproducing the duplicate. When this is done, the reproduction wavelength of each pattern reproduced from each original plate can be changed, so a multicolor part-color hologram can be obtained.

きる。In addition, three sets of *n and exposure processes are connected, and in each set of processes R. If you paste the G and B plates and set the original plate for R, G, and B and the swelling degree to reproduce those colors, the R. It is also possible to mass reproduce natural color holograms with G,83 double exposure.
なお、３重露光の場合、版とフィルムとの位置合わせを
行う必要があるので、版とフィルムとの位置合わせ装置
を設けるようにする必要がある。In the case of triple exposure, it is necessary to align the plate and the film, so it is necessary to provide a device for aligning the plate and the film.
例えば、多重露光の位置合わせ用の穴を複製用感光材料
フィルムに開け、それに合致する歯を各原版ドラム上に
設けることにより達成することができる。For example, this can be accomplished by drilling multiple exposure alignment holes in the duplicating photosensitive material film and providing matching teeth on each master drum.
また、複製感光材料フィルムにフォトポリマーを使用し
れば、明るい像が得られると共に、耐湿性にも優れてい
るので、保存性を向上させることもできる。Further, if a photopolymer is used in the photosensitive material film for reproduction, bright images can be obtained and the film has excellent moisture resistance, so that storage stability can be improved.

By irradiating the original plate with laser light from the film side, the information in the reflection hologram can be continuously reproduced in large quantities on photosensitive material film for duplication, and the photosensitive material can also be swollen and exposed using laser light of the same wavelength. By repeating this process, multicolor part color holograms and natural color holograms can be created with large IH.
