Description

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

The technical field of the present invention is hologram technology.

The present invention relates to a projector having a hologram screen

Types of screen include tripod screen, wall screen, and white screen.

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.

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.

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.

The phenomenon that a wave bends and reaches a region where it can not easily go as a particle is a diffraction

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.

Holography memory

[holography memory]

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.

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.

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.

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.

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.

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.

The problem to be solved by the present invention is that if the user attempts to view the instrument panel or the navigation device in an automobile or the like, the user must look at the instrument panel or the navigation system by turning the angle of the eye and the neck, which may increase the risk of accidents.

Therefore, while maintaining the field of view while driving, while maintaining the angle of the eyes and the angle of the neck as seen in the instrument panel and navigation system, the risk of accidents is reduced if the instrument panel and navigation system are displayed on the front.

In addition, if the instrument panel or navigation system is formed on the front side of the vehicle such as a car knit or the like, and if it is formed only when needed, the risk of an accident can be greatly reduced and the eye fatigue can be greatly reduced.

A problem to be solved by the present invention is to solve such a problem.

The hologram screen is formed on the front surface of various projectors by using a hologram and a hologram screen is provided on the front surface of the hologram screen. I want to solve the same problem.

The effect of the present invention is to project an image of a screen on a hologram projector integrally with various projectors so as to maintain the field of view during driving at night or in a car while maintaining the angle of the eyes and the angle of the neck And when the front panel and navigation are needed, it reduces the risk of accidents

In addition, when adjusting the perspective of the eyes, the instrument panel or the navigation system is formed on the front side of the automobile such as a car knit, etc., and if it is formed only when necessary by the driver's seat or voice recognition method, There is an effect that fatigue is greatly reduced.

The hologram screen can also be black with the rear part and white with the front part to prevent the rear part of the hologram screen from being reflected.

FIG. 2 illustrates a method in which a hologram screen is formed to have a large thickness with a time lag in FIG. 1, which is a method of helio display, in which a jet steam is shot in the air in a manner similar to an ultrasonic humidifier and a video image is shot thereon with a projector. When 3D content is displayed, it looks stereoscopic and the image is quite realistic.

Here, instead of helio display, the hologram screen is formed thickly with a time difference
