た。By the way, the optical contact liquid interposed between the hologram original plate and the photosensitive material is a muddy liquid and does not have a uniform thickness due to its fluidity, uneven thickness and vibration. When the amount of the contact liquid is large, there is a problem that the hologram cannot be duplicated due to the flow. Even if the hologram is copied in a clean room, dust of 10 μm or less may be mixed in. If copying is performed with the dust mixed in, the flow of the optical contact liquid around the dust and the film caused by the dust may occur. There was a problem that duplication could be hindered by the floating.

And the incident laser light interfere with each other in the duplication photosensitive material 8, and the hologram image is duplicated well. Further, when the optical contact liquid is a liquid substance composed of an ionizing radiation curable polymer, a monomer or the like, a curing reaction is caused by irradiation with ionizing radiation during or after the duplication so that it is polymerized and can be peeled from the recording film. It is also possible.

Also at this time, the excess liquid is squeezed out by a roller or the like, and the pressing device 32 presses the liquid to bring it into close contact. At this time, when the ND layer is thick and cannot be squeezed by the roller, the thickness is set to 0.1 to 1.5 mm, and the material is a polymeric material having no optical birefringence and an equal refractive index. Is used to give flexibility and allow excess liquid to be squeezed out.

After replication is complete, the AR-coated ND layer is removed and the recording film 21 is separated from the replication system by processing the original layer. Although not shown in the drawings, a radiation generator may be arranged to irradiate ionizing radiation during or after duplication to cause a curing reaction and polymerize to facilitate peeling from the recording film. The separated recording film 12 enters the drying chamber 31 and is dried in order to remove the adhered contact liquid. The dried film is collected by the take-up roller 23. These move as a series of operations and are continuously copied. It is also possible to improve productivity by attaching a plurality of these exposure units and drying units.

けることにより構成される。The present invention uses a thin and flexible ND glass, a flexible sheet, and a hard ND glass coated with a cushion layer to have a viscosity of 100 cps to 1000 cps.
The optical contact liquid of 0 cps is interposed so as to be in close contact with the photosensitive material film for duplication. When pressure is applied, pressure is uniformly applied to the optical contact liquid, so that the contact liquid is made uniform and thin. Therefore, it is possible to prevent the hologram image from being disabled due to the flow of the contact liquid. The optical contact liquid has high viscosity and low fluidity, and also serves as a cushion layer at the same time as the optical contact liquid, so even if dust is mixed in, it will be held inside and the flow of the contact liquid and the lifting of the film due to dust will be prevented. Duplication can be done without any trouble. An apparatus for carrying out such a hologram duplication method is provided with a mechanism for sending out a duplication photosensitive material film and a winding mechanism, and further, a close contact liquid drop mechanism,
It is constituted by providing a mechanism for nipping an excess of the dropped contact liquid, a mechanism for drying the contact liquid adhering to the exposed and duplicated photosensitive material for duplication, a duplicating photosensitive material film positioning mechanism, and the like.

複製を支障なく行うことができる。As described above, according to the present invention, a flexible ND glass or sheet or an optical contact liquid of ND glass having a high viscosity and a low fluidity is used, and at the same time as the contact liquid. Having a function as a cushion layer, pressure is evenly transmitted to the contact liquid to make the thickness uniform and thin, the flow of the contact liquid during exposure can be eliminated, and good holograms can be duplicated for continuous recording. By supplying a film, it is possible to improve the productivity of hologram duplication, and even if dust is mixed, it is held inside and the flow of the contact liquid and the lifting of the film due to dust are prevented,
Duplication can be done without any trouble.
