Holography is a technique for recording an image of an original object in a three-dimensional shape on the surface of a recording material similar to a photographic film by utilizing the interference effect of light caused by two separated light beams. By this holography, Is collectively referred to as a hologram.

As long as a hologram is once recorded as an image of an original object on a recording material, a stereoscopic image providing a very real sense of reality can be realized by simple reproduction of a recording material even if the original does not exist. It can be very useful when the display of the original is not easy due to problems such as storage and security.

An example of a device using a hologram is Korean Patent Laid-Open No. 2009-0103575, which is configured as shown in Fig. This technique is a method of reproducing a hologram image by projecting a video image emitted from a projector 20 onto a screen member 1 constituting a stereoscopic image unit 10 via a front screen 27, The stereoscopic image is recognized in any direction.

However, since this technique basically reproduces a planar hologram, a hologram such as a cylindrical hologram or a multiplex hologram, which records a 360 ° appearance as a complete panoramic view of the original object, There is a limit that can not be done. Since the 360 ° hologram can function as a means to replace the original object, it is urgent to develop a device capable of easily reproducing the 360 ° hologram.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the technical features of the present invention, A detailed description thereof will be omitted.

1 is a block diagram of an apparatus proposed by the present invention for reproducing a cylindrical hologram. The reproducing apparatus proposed by the present invention basically includes a main body 110, a drive plate 140, and a transparent disc 160 . Prior to describing the related configuration, it is found that the cylindrical hologram referred to in the present invention is a concept including not only a conventional cylindrical hologram but also a multiplex hologram.

The main body 110 is a portion to which the driving device 130 and the light source 180 are mounted, and is a part that supports the playback device as a whole. An upper portion of the main body 110 is opened, and a receiving space 112 is provided therein. An operation button 120 for controlling the driving unit 130 and the light source 180 is provided on the outer surface of the main body 110. The actuation button may be made of a touch panel, unlike the one disclosed.

The driving unit 130 may include a driving motor 132 and a driving wheel 134 to rotate the driving plate 140. The drive wheel 134 is preferably axially connected to the drive motor 132. Reference numeral 136 denotes auxiliary drive wheels, which may be spaced apart from each other by a predetermined distance with reference to a central portion thereof. The auxiliary driving wheel 136 supports the driving plate 140 and assists rotation.

The light source 180 is preferably provided at a central portion of the main body 110 as a portion for reproducing the cylindrical hologram 1. The light source 180 serving as a reference light is preferably composed of any one of white light selected from an incandescent lamp, a halogen lamp, and LED, and may be a monochromatic laser. In the case where the light source according to the present invention is formed of an LED or a laser, it is preferable that a diffusing lens is further provided as a means for adjusting the light emitted from the light source to a predetermined solid angle.

This is because the light emitted from the LED or laser forms a very narrow solid angle like a pencil beam. In this case, the light can not illuminate the entire cylindrical hologram 1 having a certain height, making it difficult to reproduce the complete hologram. To this end, pencil beam-shaped light is diffused within an intended angular range to illuminate the entire cylindrical hologram. Such a diffusing lens apparatus is a well-known means widely known in the related art, and a detailed description thereof will be omitted.

The driving plate 140 includes a guide hole 142 formed at a central portion and a circular plate 142 formed along the periphery of the guide hole 142, 146 are provided.

The guide hole 142 is a part for guiding the light emitted from the light source 180 to be illuminated in the cylindrical hologram 1 and the lower end of the guide hole 142 is opened so that the light source 180 can be inserted And an inverted conical structure in which the radius is increased as the whole is increased. The formation angle of the inverted cone is determined by taking into consideration the emission angle of the light source, the height of the cylindrical hologram, and the like in a comprehensive manner.

The lower surface of the circular plate 146 is in contact with the driving wheels 134 and 136 to receive a rotational force and a transparent cylinder 160 is placed on the upper surface. The present invention does not exclude the case where a plurality of standbanks 144 are provided along the outer side of the top surface of the circular plate 146 for smooth laying of the transparent cylinder 160. It is obvious that, in the case where an additional stand is provided, the number of formation and the individual vertical height can be appropriately changed.

On the other hand, the present invention does not exclude the case where the drive plate is different from the one disclosed in Fig. Specifically, the guide hole 152 is spaced apart from the first inverted cone 151 by a predetermined distance from the first inverted cone 151 and spaced apart from the first inverted cone 151 by a predetermined distance And a second inverted cone 153 configured to increase in width. That is, the light emitted from the light source 180 is guided through the space between the first inverted cone 151 and the second inverted cone 153. This arrangement allows the light emitted from the light source to be more concentrated in the cylindrical hologram.

The transparent cylinder 160 is a portion where the cylindrical hologram 1 is closely contacted and rotates together with the drive plate on the upper side of the drive plate 140 and the cylindrical hologram 1 is in close contact with the inner surface thereof. If it can only be made transparent, its material is not limited.

In the present invention, the cylindrical hologram 1 can be mounted on the inner surface of the transparent disc without any intermediary means. In addition, as shown in FIG. 1, And a cylindrical hologram is mounted.

The transparent protective plate 170 is positioned inside the transparent disc 160 and is placed on the driving plate 140 and rotates together with the driving plate and the transparent disc according to the rotational motion of the driving plate. The cylindrical hologram 1 may be disposed on the transparent disc 160 and the transparent protection plate 170. In this case, In this case, the cylindrical hologram is more securely protected from the external environment. There is no limitation on the material of the transparent protective plate if it is made transparent similarly to the transparent disc.

A schematic operation configuration of the apparatus having the above-described configuration will be described with reference to FIG. 2 and the description of each of the above-described configurations. Here, the drive plate assumes the configuration disclosed in Fig.

First, the cylindrical hologram 1 is brought into close contact with the inner surface of the transparent disc 160, and then the operation button 120 is pressed to sequentially operate the light source 180 and the driving device 130. When the light source 180 is activated, the light emitted from the light source is projected onto the cylindrical hologram 1 which is in close contact with the inner surface of the transparent disc 160 through the guide hole 142 of the driving plate 140.

The emitted light is reference light, and when this reference light is projected onto the cylindrical hologram 1, the recorded hologram is reproduced. On the other hand, since the cylindrical hologram 1 rotates at a constant speed with respect to the observer O in accordance with the rotational motion of the driving plate 140, the observer rotates 360 degrees in the original hologram 1 recorded in the cylindrical hologram 1 ° You will be able to enjoy the entire image. This is because the hologram as a virtual image for the target original is felt to be present inside the reproducing apparatus in view of the observer because the present invention assumes the transmissive hologram.

4 shows another configuration of an apparatus for reproducing a cylindrical hologram according to the present invention. This embodiment is different in that the light source is located on the upper part of the transparent disc rather than the inside of the main body.

A vertical support 292 having a predetermined height fixed to the outer surface of the body 210 and a horizontal support 296 extending from the other end of the vertical support plate 292 toward the center of the transparent circular plate 260 The light source 280 is attached to the end of the horizontal support 296 of the mount 290. The light is transmitted through the cylindrical hologram 1 And is projected from above.

Since the light source 280 is mounted on the separate mounting table 290, the driving plate 240 is not required to have a guide hole, And the driving unit 230 is mounted inside the main body 210 is the same as the above-described embodiment. In addition, it is also possible to further include a transparent protective plate 270 inside the transparent disc 260.

In addition, in forming the light source 280, it is also possible to further include a diffusing lens so as to limit the outgoing angle of light as the reference light to be emitted downward into the cylindrical hologram 1, within the range of three-dimensional angles originally intended. This embodiment is the same as the operation configuration of the above-described embodiment except that the light is emitted downward at a certain angle in the light source, so that a description thereof will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be apparent that the present invention can be practiced with added features.
