Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a color hologram telegram, and more particularly, to a telegram in which a color hologram is affixed to a part of the telegram to improve design and the like.
[0002]
[Prior art]
Conventionally, it is well known that a telegram is accompanied by a pressed flower or embroidered.
However, these telegrams have limitations in terms of design.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of such a current state of the art, and its purpose is to make it possible to display a three-dimensional image or the like by attaching a color hologram to the telegram so that the design, surprise, and attention of the telegram can be improved. It is to increase.
[0004]
[Means for Solving the Problems]
The color hologram telegram of the present invention that achieves the above object is characterized in that a color hologram capable of reproducing white light is attached to a part of a mount of a telegram having a spread configuration.
[0005]
In this case, there is a color volume hologram as the color hologram. In that case, it is desirable that it is recorded on a single hologram layer.
[0006]
Further, the color hologram may be a relief type and reflection type rainbow hologram.
[0007]
In addition, a miniature light bulb is attached at a position facing the color hologram when it is in a half-open state, and a paper battery and a switch that is closed when the telegram is opened are built in, and the miniature light bulb is connected to the battery via the switch. It is more preferable that the connection is made.
You may make it add variable information to the above color hologram.
[0008]
In the present invention, a color hologram capable of reproducing white light is affixed to a part of the telegram mount in a spread configuration, so that the person who received the telegram can read the color object, characters, etc. recorded in the color hologram. It can be observed and the design, unexpectedness, and attention of telegrams can be enhanced.

DETAILED DESCRIPTION OF THE INVENTION
The color hologram telegram of the present invention will be described below based on examples.
In some embodiments of the present invention, a hologram called a volume hologram or a Lippmann hologram is used. The recording method and the reproducing method of the volume hologram will be described with reference to FIG. For recording a volume hologram, as shown in FIG. 6A, when a volume hologram recording material 1 such as a photopolymer is used and a three-dimensional object O to be recorded is illuminated with illumination light 2, scattered light 3 from the object O Therefore, the scattered light 3 (object light) is incident from the back surface side of the recording material 1, and the reference light 4 that is coherent with each other at the same wavelength as the illumination light 2 is incident from the front surface side of the recording material 1. Both light beams 3 and 4 are caused to interfere in the recording material 1 and the interference fringes are recorded in the recording material 1. At this time, the illumination light 2 and the reference light 4 are recorded as light including three wavelengths of R (red), G (green), and B (blue) at one time, or the recording material 1 and the object O are left as they are. 2 and the wavelength of the reference light 4 are sequentially changed to R, G, and B, and recording is performed three times on one recording material 1, thereby obtaining a color volume hologram 1 ′.
[0010]
After recording, when the color volume hologram 1 ′ subjected to sensitization or the like is irradiated with white light 5 as shown in FIG. 6B, diffracted light 6 is generated from the volume hologram 1 ′, and the diffracted light. 6 reproduces the recorded color stereoscopic image O ′ of the object O as a virtual image, so that this color stereoscopic image O ′ can be seen by the eyes E of the observer.
[0011]
In one embodiment of the color hologram telegram according to the present invention, as shown in FIG. 1, such a color volume hologram 1 ′ is pasted on one surface 12 of the open surface of the telegram 10 that is spread along the broken line 11. . A miniature light bulb 14 is attached to a part of the other surface 13 of the open surface, and a paper battery 15 is built in any position of the telegram 10, so that the battery 15 and the miniature light bulb 14 are 12 and the surface 13 are connected via a switch 16 that is closed when the surface 13 is opened. Reference numeral 17 denotes a telegram.
[0012]
In such a telegram 10 of the present invention, as shown in FIG. 2, when the half-folded surface 12 is expanded by approximately 90 °, the switch 16 is closed and the miniature light bulb 14 on the surface 13 is turned on, and the illumination light 18 is emitted. Since the illumination light 18 illuminates the color volume hologram 1 ′ on the other surface 12, the person who received the telegram receives the color object, character, for example, congratulations recorded on the color volume hologram 1 ′. Can observe three-dimensional records of cranes and tortoises or the letter “壽”, and three-dimensional records of flowers in Soden.
[0013]
In order to reduce the total thickness of such a color volume hologram 1 ′, a hologram layer that forms a color volume hologram by multiplex recording with R, G, and B3 wavelengths is formed as a single layer. FIG. 3 shows a cross-sectional view of an example of the layer structure of the color volume hologram 1 ′. The color volume hologram 1 ′ is adhered to a base material 21 made of, for example, paper for telegrams. The adhesive layer 22 from the side of the base material 21, the volume hologram layer 20 made of a single-layer photopolymer, etc., and the adhesive layer 23. The volume hologram layer 20 has a thickness of 25 μm or less, for example, 15 μm, and the adhesive layers 22 and 23 have a thickness of 20 μm or less, for example, 15 μm. The layer 24 has a configuration of 25 to 50 μm.
[0014]
By the way, as described above, in order to give the telegram a design, surprisingness, and attention to the color volume hologram 1 ′, a color object, characters, and the like are recorded in advance in three-dimensional form. It is also possible to write variable information such as a message, address, picture, etc. using a laser beam. This is shown in FIG. When a laser beam 25 such as infrared light is incident on the color volume hologram 1 ′ attached to the telegram 10, the irradiation position of the volume hologram layer made of photopolymer becomes cloudy and visible. The laser beam 25 can be deflected and scanned to write a predetermined character or the like, thereby improving the design and the like.
[0015]
Incidentally, as a color hologram capable of reproducing white light, there is a rainbow hologram in addition to a volume hologram. This hologram is a kind of image hologram, and can be reproduced as white light by restricting information in the vertical direction by a slit, and becomes a pseudo color hologram. This rainbow hologram can be configured as a relief type reflection type hologram. FIG. 5 shows a schematic cross-sectional view thereof. Relief type holograms record interference fringes as relief patterns on a relief hologram recording material such as photoresist, and the relief pattern is transferred using a photopolymer or the like. 27 is formed. By providing a reflective layer 28 of aluminum or the like on the relief pattern 27 by a technique such as vapor deposition, a relief-type reflective rainbow hologram 30 is formed. By sticking such a relief-type reflection-type rainbow hologram 30 in place of the color volume hologram 1 ′ shown in FIG. 1, the color pattern recorded therein can be obtained in the same manner as in FIGS. The person who received the telegram can observe it.
[0016]
Also in the case of this relief type and reflection type rainbow hologram 30, as shown in FIG. 5, a predetermined character or the like can be additionally written by deflecting and scanning a laser beam 25 of infrared rays or the like. In this case, since the laser beam 25 destroys the reflection layer 28 of the rainbow hologram 30 by condensation or the like, the reflection characteristics of the irradiation position appear to change, so that variable information can be written later. .
[0017]
Further, as shown in FIG. 1, the relief-type reflection rainbow hologram 30 may be further pasted on a part of the color volume hologram 1 ′ pasted on the telegram 10.
[0018]
As described above, the color hologram telegram of the present invention has been described based on the embodiments. However, the present invention can be modified in various ways limited to these embodiments. Of course, a color image recorded on a color hologram by external light may be observed without providing a paper battery and a switch.
[0019]
