BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hologram display apparatus for reproducing a hologram recording plate mounted therein using illumination, and more particularly to a hologram display apparatus for selectively reproducing a transmission type hologram and a reflection type hologram using a single display mechanism. .

Holography is a next-generation media technology capable of recording stereoscopic images as a technique developed during experiments to improve the resolving power of an electron microscope. The sunlight or the ordinary light source is an aggregate of various wavelengths, and the phases of the respective wavelengths are different. However, since the light generated by the laser (hereinafter referred to as a laser) is a continuous wave whose phases are completely matched with each other, That is, a laser is divided into an object beam and a reference beam, and then the laser beam is irradiated to the object, and the light (object light) diffused and reflected by the object and other light (reference light) traveling independently of the object, Is simultaneously irradiated to the hologram recording plate to record the subject image.

When the hologram recording plate is irradiated with the same light as the reference light used in the photosensitive process, the object image is recorded as a stereoscopic image The reproduced image is called a hologram. Since the hologram provides a three-dimensional stereoscopic image exactly the same as the subject, it is very appropriate to use such a holography if it is difficult to realistically display an actual object such as an object or cultural property that can not be viewed as a stereoscopic image such as a photograph or a picture.

Among the techniques proposed for using the holography-based display device are Korean Patent Publication No. 2007-0111495 and Korean Patent Publication No. 2011-0128771. FIG. 5 shows an example of the former. This technology is such that when the projector 1102 forms an image on the image plane 1101, the reflection mirrors 1601, 1602, 1603, and 1604 of the pyramid structure installed below the image plane 1101 And provides an image to the viewer located inside. 6 is a view showing an example of the latter. This technique is a method of providing an image generated by the image processing apparatus 300 to the spectator through the semitransparent glass 210 when the image generated by the monitor 230 is image- to be.

The former may not be more realistic in terms of installation and operation because it may be possible to implement a more stereoscopic hologram, but the device itself is too large. On the other hand, in the latter, the size of the device itself is considerably reduced, so it seems to be somewhat realistic compared with the former. However, this technique is also required to have a complicated image processing device, And it is possible to reproduce only one kind of transmission type hologram even if it is used.

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 shows a schematic configuration diagram of a hologram display mechanism according to the present invention. As shown in the drawings, the present invention is characterized in that it includes a lower and upper frames 10 and 20, a side transparent window 30, a side illuminating device 40, and a central illuminating device 50. Hereinafter, each of these configurations will be described.

The lower frame 10 is a part for supporting the entire apparatus, and includes a lower plate 12, a lower frame 14, and a lower mounting end 16.

The lower plate 12 is formed of a rectangular flat plate. The lower rim 14 is vertically provided on each side of the upper plate 12 and has a predetermined height. The lower mounting end 16 is provided at a central portion of a pair of lower rims facing each other in the lower rim 14. The lower mounting stage 16 is a portion where the first and second reflection type hologram recording plates are mounted. Each of the lower plate and the lower frame may be integrally formed, and the material thereof may be any one of synthetic resin, metal, and wood.

The upper frame 20 is spaced apart from the lower frame 10 by a predetermined distance and includes an upper frame 22 and an upper frame 24. The upper panel 22 may have a rectangular shape like the lower panel 12. The upper panel 24 has a predetermined height at each side of the upper panel 22 and is vertically downward. The structure and material of the top plate are the same as those of the bottom plate.

The side transparent window 30 is installed between the upper and lower frames 10 and 20 and is vertically installed on each of the upper and lower edges 14 and 24. The side transparent window 30 is a part where the transmission type hologram recording plate is mounted, and is preferably made of a transparent material such as synthetic resin or glass.

In installing the side transparent window 30, the present invention mediates a vertical support 70 between the mutually opposing edges of the lower frame 10 and the upper frame 20, respectively, as shown in the figure, The case where the side transparent window 30 is provided on the side wall 70 is not excluded. To this end, an insertion end 72 for inserting both end portions of the side transparent window 30 is provided on both sides of the vertical support 70. In addition, a mounting end 76 is provided on one side of the insertion end 72, Can be provided. The mounting stage 76 is a portion for mounting the transmission type hologram recording plate. The mount may be made of a synthetic resin or a metal such as aluminum.

The side illuminating device 40 is provided at a central portion of the inner surface of the upper plate 22 of the upper frame 20 and includes a side illuminating light source 42. The side illumination light source 42 irradiates a transmissive hologram recording plate placed on at least one side transparent window selected from the side transparent window 30 or a transmissive hologram recording plate placed on all the side transparent windows. The side illumination light source 42 may be made of any one of a conventional backlight such as a halogen or a laser.

On the other hand, as a configuration for irradiating all the side transparent windows, the present invention proposes a case where the side illumination light sources 42 are composed of four as shown in FIG. In this case, it is preferable that the respective side irradiation light sources 42 are disposed at a predetermined distance from each other and are inclined downward at a predetermined angle so as to irradiate each side transparent window. In the case where the number of the side illumination light sources is four, it is assumed that there are four side transparent windows. It is obvious that the number of the side transparent windows may vary depending on the number of side transparent windows. It is needless to say that although each of the side illumination light sources is composed of four, these side illumination light sources can be individually controlled.

The central irradiating device 50 includes a pair of a first central irradiation light source 52 and a second central irradiation light source 56 disposed at mutually opposite positions. Specifically, the first central irradiation light source 52 may be installed at a central portion of the inner surface of the upper rim of the upper frame 20 selected from the upper rim 24, And may be installed at a central portion of the inner surface of the upper rim facing the upper rim on which the first central irradiation light source 52 is installed.

Each of the first and second central irradiation light sources 52 and 56 is means for reproducing the first and second reflection type hologram recording plates which are mounted on the lower mounting stage 16. That is, when the side transparent window is divided into the first, second, third, and fourth side transparent windows, the first central illumination light source 52 reproduces the first reflective hologram recording plate to form the first side transparent window And the second central irradiation light source 56 reproduces the second reflection type hologram recording plate to show the hologram through the third side transparent window (or the fourth side transparent window). Each of the first and second central irradiation light sources 52 and 56 may be made of any one of a conventional light source such as a halogen or a laser as the side irradiation light source 42.

The actuating device 60 is provided on one side of the upper frame 20 with a plurality of buttons 62 provided thereon. The button 62 is a part for operating the side illuminating device 40 and the central illuminating device 50, respectively. The operating device 60 may be a conventional button type or a touch screen type. Each of the light sources of the side illuminating device 40 and the central illuminating device 50 can be operated by either a power source or a battery.

The schematic operating configuration of the present invention having the above-described configuration will be described with reference to the above description and FIGS. 3 and 4, respectively.

First, a case of reproducing a reflection hologram using the present invention will be described. The first and second reflection type hologram recording plates (Reflection Hologram Plate 1 / RHP1, Reflection Hologram Plate 2 / RHP2) for reproduction are mounted on the lower mounting stage 16 with the upper frame 20 removed. The first and second reflection type hologram recording plates may be formed of a film or a glass substrate. When each of the first and second reflection type hologram recording plates RHP1 and RHP2 is mounted on the lower mounting stage 16, the upper frame 20 is returned to its original position, and then the operation device 60 is operated, The first and second central irradiation light sources 52 and 56 are turned on.

When the first and second central irradiation light sources 52 and 56 are turned on, the light generated in each of the first and second central irradiation light sources, as shown in FIG. 3, passes through the first and second reflection light sources Shaped hologram recording plates RHP1 and RHP2 and then reflected and diffracted by each of the first and second reflection type hologram recording plates to pass a hologram to a spectator positioned in front of each side transparent window 30 do. That is, each spectator viewing the other side transparent window at positions opposite to each other is provided with first and second reflection type holograms (Reflection Hologram 1 / RH1, RH2) recorded and reproduced in the first and second reflection type hologram recording plates RHP1 and RHP2, Reflection Hologram 2 / RH2).

Next, a case in which a transmission hologram is reproduced using the present invention will be described. The first, second, third and fourth transmissive hologram recording plates (Transmission Hologram Plate 1 / THP 1, Transmission Hologram Plate 2 / THP 2, and Transmission Hologram) for reproduction in a state in which the upper frame 20 is separated, Plate 3 / THP 3, Transmission Hologram Plate 4 / THP 4) are mounted on the mounting end 76 of each vertical support 70. The first, second, third, and fourth transmissive hologram recording plates may be formed of a film or a glass substrate.

When the first, second, third and fourth transmissive hologram recording plates THP1, THP2, THP3 and THP4 are respectively mounted on the stationary ends 76 of the vertical supports, the upper frame 20 is returned to its original position, To illuminate the respective side irradiation light sources 42 of the side irradiation device 40. The first, second, third and fourth transmissive hologram recording plates THP1, THP2, THP3 and THP4, which are formed by the light emitted from the respective side irradiation light sources, So that the hologram is provided to the spectators positioned in front of the respective side transparent windows 30 located on the back side thereof.

FIG. 4 shows an example of a hologram formed by the first and third transmission hologram recording plates THP1 and THP3 among the first, second, third and fourth transmissive hologram recording plates THP1, THP2, THP3 and THP4. In other words, each spectator who views the other side transparent window in a state of being opposed to each other can view the first and third transmissive holograms (Transmission Hologram 1 / TH1, Transmission Hologram) reproduced and recorded on the first and third transmissive hologram recording plates THP1 and THP3 3 / TH3). Each of the second and fourth transmission holograms (Transmission Hologram 2 / TH2, Transmission Hologram 4 / TH4) recorded and reproduced in the second and fourth transmission hologram recording plates (THP2 and THP4) Of course.

As described above, the present invention can generate and provide the same hologram to a plurality of viewers, or provide different holograms, and can selectively provide any one of the reflection hologram and the transmission hologram to the spectator.
