Description

[0001] The present invention relates to a projector equipped with a hologram screen,

본 발명의 기술분야는 홀로그램 기술이다.The technical field of the present invention is hologram technology.

본 발명은 홀로그램 스크린이 구비된 영사기로서The present invention relates to a projector having a hologram screen

스크린의 종류로는 삼각대 스크린,벽걸이 스크린,화이트 스크린등이 있다. Types of screen include tripod screen, wall screen, and white screen.

최근에 홀로(전체)그래피(기록하다) 기술이 각 분야에서 응용되면서부터 홀로그래피라는 말이 널리 알려지게 되었으나, 홀로그래피의 원리는 비교적 오래 전부터 알려져 있었던 것으로, 1948년 D.가보가 전자현미경의 분해능력을 향상시킬 목적으로 생각해낸 영상방법이 홀로그래피 기술이다.Holography has been widely known since the application of holographic technology in each field. However, the principle of holography has been known for a long time, and in 1948, D. Gabo discovered the disassembly ability of electron microscope The holographic technique is the imaging method thought to improve.

홀로그래피 영상은 앞 뒤 전 후 좌 우 360도 전체에서 모든 영상을 찍기 때문에 영상을 안경을 끼지 않고도 앞뒤 옆면을 모두 볼 수 있다.Because holography images take all the images in front, back, front, back, left, and right of 360 degrees, you can see both front and back sides without wearing glasses.

레이저에 의해서 홀로그래피 영상을 만드는데 레이저는 어떤 물체에 반사되면 회절이 되어서 다시 나온다. 이 회절이 되어서 나오는 그 영상에 모든 물체의 입체 영상이 담겨 있다. 그것을 화면에 기록해서 원래의 레이저를 비춰 주면 그 녹화되어 있는 입체 영상의 정보가 그대로 실물과 같이 똑같이 비춰 지는 그런 원리이다.A laser produces a holographic image. When a laser is reflected on an object, it is diffracted and comes out again. In this image coming out of this diffraction, a stereoscopic image of all objects is contained. If you record it on the screen and shine the original laser, then the information of the recorded stereoscopic image is exactly the same as the real thing.

파동이 입자로서는 도저히 갈 수 없는 영역에 휘어져 도달하는 현상이 회절인데 The phenomenon that a wave bends and reaches a region where it can not easily go as a particle is a diffraction

현재의 기술 수준은 스틸(정지)영상은 액자 수준까지 가능하며 광고. 전시, 홍보등에 이용되고 있다. 유사 홀로그램으로서는 해외에서는 20인치(약 50.8cm)까지 구현이 된 사례가 있다.The current level of technology can be up to frame level with still images. Exhibition, and publicity. As a similar hologram, there has been a case where 20 inches (about 50.8 cm) is realized in overseas.

홀로그래피 메모리Holography memory

[ holography memory ] [holography memory]

홀로그래피 기술을 응용하여 대용량의 디지털 정보나 영상을 기록하고 재생하는 메모리. 홀로그래피는 2차원의 기록 매질에 3차원 물체 영상을 기록하고 재생하는 기술로서 빛의 세기뿐만 아니라, 파동으로서의 빛이 갖는 위상(phase)까지 기록하기 때문에 3차원 상을 재현할 수 있다. 특정 좌표의 밝기 정보를 한 점(Bit)씩 일일이 저장하던 기존 방식과 달리 홀로그래피 메모리는 평면의 전체 정보를 한 점에 기록하는 페이지 지향 메모리(Page-Oriented Memory)방식을 사용한다. 물체의 이차원적인 정보를 완벽하게 가지고 있는 이러한 한 점 정보들을 회전 거울을 이용하여 다각도로 수집하여 저장함으로써 대용량의 3차원 세계를 저장할 수 있게 된다. 홀로그래피 메모리는 디지털 비디오 디스크(DVD)보다 150배 빠른 속도와 테라바이트 급의 대용량이 가능할 것으로 보고 있다.A memory that records and reproduces large amounts of digital information or images by applying holography technology. Holography is a technique for recording and reproducing a three-dimensional object image on a two-dimensional recording medium, and it is possible to reproduce a three-dimensional image because not only the intensity of light but also the phase of light as a wave is recorded. Unlike the conventional method in which the brightness information of a specific coordinate is stored one by one , the holographic memory uses a page-oriented memory method in which the entire information of the plane is recorded at one point . This point information, which has two-dimensional information of an object perfectly, can be stored in a multi-angle by using a rotating mirror, and it is possible to store a large-capacity three-dimensional world. Holographic memory is expected to be 150 times faster than digital video discs (DVDs) and capable of large terabytes.

Beam Splitter에 입사한 Laser는 기준광과 물체광으로 나누어 지고 물체광은 입력된 Data에 따라서 픽셀들이 이루는 명암의 2진 Data의 한 Page 단위로 공간 광변조기( SLM: Spatial Light Modulator)에 의해서 변조되고, 이때 각각의 Page에는 회전 거울( Rotating Mirror) 의 각도를 조금씩 달리하는 기준광이 상응하게 작성된다. 이후 물체광과 기준광은 홀로그램을 기록하기 위한 저장 매체 내부에서 간섭을 일으키고 이때 발생하는 간섭무늬의 강도에 따라서 저장 매체 내부의 운동전하( Mobile Charge)의 광유도 현상이 발생 하고 이러한 과정을 통하여 간섭무늬가 기록된다. 저장 매체에 기록된 Data를 읽어 내기 위해서는 기준광만을 저장 매체에 조사하면 간섭무늬는 기준광을 회절시켜 원래의 픽셀의 명암으로 구성되는 바둑판 무늬로 복원되고 이후 읽어진 상을 CCD(Charge Coupled Device) 위에 비추어 원래의 Data로 복원하게 된다. 이때 각각의 기준광은 기록시와 동일하도록 회전 거울에 의해서 각도가 조절되어야 한다. 이와 같이 재생시 기준광은 기록시 사용된 기준광과 반드시 정확히 일치하도록 해야 하므로 회전 거울을 회동시키는 기구의 각도 분해능에는 엄격한 정밀도가 요구된다. The laser incident on the beam splitter is divided into a reference light and an object light. The object light is modulated by a spatial light modulator (SLM) in units of one page of light and dark binary data composed of pixels according to the input data, In this case, a reference light is generated corresponding to each page with a slightly different angle of the rotating mirror. The object light and the reference light then interfere with each other in the storage medium for recording the hologram. Depending on the intensity of the interference fringes generated at this time, the light charge phenomenon of the mobile charge inside the storage medium occurs, Is recorded. In order to read the data recorded on the storage medium, when only the reference light is irradiated to the storage medium, the interference fringe diffracts the reference light, restores to a checkered pattern composed of light and shade of the original pixel, and then reads the read image on a charge coupled device The original data is restored. At this time, the angle of each reference light should be adjusted by a rotating mirror so that it is the same as that in recording. As described above, since the reference light must be exactly matched with the reference light used for recording, strict resolution is required for the angular resolution of the mechanism for rotating the rotating mirror.

이러한 정밀도는 저장 물질인 Crystal의 두께에 크게 의존하는데 Crystal의 두께가 두꺼워 질수록 더욱 정확한 정밀도가 요구된다. 만약 Crystal의 두께가 1 Centimeter인 경우 재생시 회전 거울에 의한 기준광의 조사 각도가 기록시 기준광의 조사 각도에 비해서 1/1000 도만 편향되어도 재생 Image는 완전히 사라지고 말게 된다. 기록시 Data의 첫Page를 Crystal에 기록한 후, 기준광의 각도를 첫번째 홀로그램의 재생 복원상이 완전히 사라질 때까지 증가시키고 이때 다시 새로운 Data Page를 입력시켜 Crystal에 기록하게 된다. 이러한 과정을 Angle Multiplexing이라고 하며 이 과정의 반복을 통하여 Data를 Crystal 내부에 중첩 기록하게 되는 것이다.This accuracy depends heavily on the thickness of the crystal, the storage material, and the thicker the crystal, the more precise the accuracy is required. If the thickness of the crystal is 1 centimeter, the reproduction image is completely lost even if the irradiation angle of the reference light by the rotating mirror during reproduction is deviated by 1/1000 from the irradiation angle of the reference light during recording. After recording the first page of the data in the crystal at the time of recording, the angle of the reference light is increased until the reconstruction image of the first hologram disappears completely. At this time, a new data page is inputted and recorded in the crystal. This process is called Angle Multiplexing, and the data is overwritten in the crystal by repeating this process.

리얼 홀로그램이 등장한 것은 2006년 일본에서다. 당시 시연했던 리얼 홀로그램은 단색의 영상을 허공에 띄워 1초에 10~15 프레임 정도의 영상을 띄울 수 있는 방식이었다. 허공에 5만개 정도의 빛을 쏴서 점으로 이뤄진 영상을 입체적으로 보여주는 방식인데, 현재는 사실적 표현에 가까운 초당 24~30 프레임 정도를 보여줄 수 있는 수준에 도달했다. 하지만 트루컬러로 실물과 같은 영상을 보여주기에는 아직 넘어야 할 산이 많아 보인다.The real hologram appeared in Japan in 2006. The real hologram that was demonstrated at the time was a way to float a monochromatic image in the air and display images of 10 to 15 frames per second. It is a way of showing three-dimensional images of points made by shooting about 50,000 lights in the air, but now it reaches a level that can show about 24-30 frames per second close to realistic expression. However, it seems that there are still many mountains to show in real color.

리얼 홀로그램은 아니지만 공중에 영상을 띄우는 기술은 이미 미국에서는 다른 방법으로 상용화가 되어 사용되고 있다. Although it is not a real hologram, the technique of displaying images in the air has already been used in the US as a commercial method.

헬리오 디스플레이라는 방식이 있는데 공기 중에 초음파 가습기와 비슷한 방식으로 제트 수증기를 쏘고 그 위에 프로젝터로 영상을 쏘는 방식이다. 3D 콘텐츠를 띄우면 입체적으로 보이며 영상도 상당히 실제적이다. 정면으로 봐야만 제대로 영상을 감상할 수 있다는 단점이 있고 수증기를 발생시키는 장치가 있어야 하므로 늘 물이 필요하고 정해진 공간에서만 볼 수 있다는 단점이 있지만 유리막이나 투명 필름처럼 공간을 막고 있는 방식이 아니라서 패션쇼나 뮤지컬 공연 등의 분야에서 최근 사용이 증가하고 있다.There is a method called helio display, in which the jet steam is shot in the air in a manner similar to the ultrasonic humidifier, and the image is shot with the projector on it. When 3D content is displayed, it looks stereoscopic and the image is quite realistic. There is a disadvantage in that it can only view the image properly if it is seen from the front, and there is a device that generates water vapor, so it is always necessary to have water and can only be seen in a predetermined space. However, this is not a method of blocking space like a glass film or a transparent film. And the performance has been increasing recently.

본 발명은 홀로그램으로 스크린을 전면에 형성하여 프로젝터가 영사대나 브라켓, 스크린, 프로젝터 램프등을 설치해야 되는 불편함 없이 프로젝터나 각종 영사기에서 홀로그램 스크린이 전면에 형성이 됨으로써 간편하게 영상을 즐길 수 있다.The present invention can easily enjoy images by forming a holographic screen on a projector or various projectors without inconveniencing the projector having a projection screen, a bracket, a screen, and a projector lamp by forming a screen with a hologram on the front surface.

홀로그램의 용도와 가능성에 대해서 보면Looking at the uses and possibilities of holograms

주변에서 가장 쉽게 볼 수 있는 것은 신용카드에 붙어 있는 홀로그램이다. 신용카드에는 위조 방지를 위하여 반사형 홀로그램이 붙어 있다. 그래서 카드의 고유한 문양을 표현한 3차원 입체영상을 눈으로 확인할 수 있다. 또한 저장 매체로도 사용되고 있다. 홀로그램은 평면의 정보를 한 점에 기록하는 것이기 때문에 창문을 통하여 방안을 들여다보듯이 홀로그램의 작은 조각으로도 전체 홀로그램의 모습을 재현할 수 있다. 홀로그램에 저장된 정보는 오염이나 파손에 매우 잘 견딜 수 있고, 용량면에서도 다른 저장 매체에 비해 우수하다. 나아가서는 연속적인 영상을 재현하는 방법에 대한 연구가 이루어진다면 홀로그램을 이용한 영화제작도 가능하며 사람의 골격구조를 입체적으로 관찰할 수 있으므로 의학적 용도로도 사용가능하다. 이밖에도 건축, 자동차 설계 등 각 분야에서 다양하게 활용이 가능하다.The easiest thing to see around you is a hologram on your credit card. The credit card has a reflective hologram to prevent forgery. Therefore, the 3D stereoscopic image expressing the unique pattern of the card can be visually confirmed. It is also used as a storage medium. Since the hologram records the information of the plane in one point, the whole hologram can be reproduced with a small piece of the hologram as if looking through the window through the window. The information stored in the hologram can withstand contamination or breakage, and is superior in capacity to other storage media. Furthermore, if a method of reproducing a continuous image is performed, it is possible to make a film using a hologram, and it can be used for medical purposes because a human skeletal structure can be observed in three dimensions. In addition, it can be used in various fields such as architecture and automobile design.

홀로그래피의 특징에 대응한 응용분야가 대단히 광범위하다. 또한 홀로그래피는 렌즈를 사용하지 않고 광원상을 결상시킬 수 있으며, 피사체를 조명하는 방법이나 참조광을 쬐는 방법, 그리고 광원이나 감광재료에 따라서 많은 방법이 개발되어 있다. The application fields corresponding to the characteristics of the holography are very wide. In addition, holography can form a light source image without using a lens, and many methods have been developed depending on a method of illuminating a subject, a method of illuminating a reference light, and a light source or a photosensitive material.

한 홀로그램에 다른 화상을 다중기록(多重記錄)하여 한꺼번에 재생할 수 있는 다중정보처리(多重情報處理)를 할 수 있는 기능이 있으며, 또 입체상(立體像)을 재현시킬 수 있기 때문에, 입체 텔레비전도 가능할 것이며, 영화필름을 홀로그램으로 전환시켜 놓았다가 필요에 따라 재생시키면 필름의 손상이나 먼지가 전혀 없는 셀렉터비전이 가능하다든지, 단파장광으로 촬영한 홀로그램을 장파장광으로 쬐어 보면 상이 확대되어 보이기 때문에 X-선 현미 홀로그래피로서 생체 내부를 분자정도의 크기로 입체적으로 볼 가능성도 있다. There is a function that can perform multiple information processing (multiple information processing) capable of reproducing multiple images simultaneously in one hologram and reproducing them all at once, and since stereoscopic images can be reproduced, stereoscopic television If you convert a movie film to a hologram and reproduce it if necessary, you can see a selector vision that does not damage the film or dust at all. If you look at a hologram shot with a short-wavelength light with a long wavelength, It is also possible to see the interior of the living body as a three-dimensional image of a molecular size.
