Description

Projector equipped with hologram screen}

The technical field of the present invention is hologram technology.

The present invention is a projector equipped with a hologram screen

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

In recent years, holography (record) technology has been widely known as holography since its application in various fields, but the principle of holography has been known for a long time. Holographic technology is an imaging method conceived for the purpose of improvement.

Holographic images take all images from front to back, front to back and right to 360 degrees, so you can see the front and back sides without wearing glasses.

The laser produces a holographic image, which is diffracted when it is reflected by an object and comes out again. The image produced by this diffraction contains a stereoscopic image of all objects. If you record it on the screen and shine the original laser, the information of the recorded stereoscopic image is reflected as it is.

The diffraction phenomenon is that the wave bends and reaches a region that the particles cannot reach.

The current level of technology is that still (still) video can be framed and advertised. We are used for display, public information. Similar holograms have been implemented in foreign countries up to 20 inches (about 50.8 cm).

Holography memory

holography memory

Memory that uses holography technology to record and play large amounts of digital information or video. Holography is a technique for recording and reproducing a three-dimensional object image on a two-dimensional recording medium. As a result, not only the intensity of light but also the phase of light as a wave can be recorded to reproduce a three-dimensional image. Unlike conventional methods that store brightness information of specific coordinates one by one , holography memory uses a page-oriented memory method that records the entire information of a plane at one point . This one-point information, which has two-dimensional information of the object, is collected and stored at various angles using a rotating mirror, thus storing a large three-dimensional world. Holographic memory is expected to be 150 times faster than digital video discs (DVDs) and capable of terabytes of capacity.

The laser incident on the beam splitter is divided into the reference light and the object light, and the object light is modulated by a spatial light modulator (SLM) in units of a page of binary data of contrasts formed by pixels according to the input data. At this time, each page has a corresponding reference light which slightly changes the angle of the rotating mirror. Afterwards, the object light and the reference light cause interference in the storage medium for recording the hologram, and the light induction of the mobile charge in the storage medium occurs according to the intensity of the interference pattern generated. Is recorded. In order to read the data recorded in the storage medium, only the reference light is irradiated to the storage medium, and the interference pattern is diffracted by the reference light and restored to the checkered pattern composed of the contrast of the original pixel. In light of this, the original data is restored. At this time, the angle of each reference light should be adjusted by the rotating mirror to be the same as in recording. Since the reference light at the time of reproduction must exactly match the reference light used at the time of reproduction, strict precision is required for the angular resolution of the mechanism for rotating the rotating mirror.

This precision is highly dependent on the thickness of the crystal, which is a storage material. The thicker the crystal, the more precise the precision. If the thickness of the crystal is 1 centimeter, the playback image will disappear completely even if the angle of irradiation of the reference light by the rotating mirror during the playback is biased only 1/1000 degrees compared with the angle of irradiation of the reference light at the time of recording. After recording the first page of data in the crystal, the angle of the reference light is increased until the reconstructed image of the first hologram disappears completely. At this time, the new data page is input again and recorded in the crystal. This process is called angle multiplexing, and the process is repeated to record data inside the crystal.

The real hologram appeared in Japan in 2006. The real hologram that was demonstrated at the time was a way of displaying a monochromatic image in the air and displaying 10-15 frames per second. It shoots 50,000 light in the air and displays the image made of dots in three dimensions. Currently, it has reached the level of 24 to 30 frames per second which is close to the realistic expression. However, there is still a lot of mountains to overcome in order to show the real picture in true color.

Although not a real hologram, the technique of displaying images in the air is already being used in other ways in the United States.

There is a method called helio display that shoots jet steam in the air in a similar way to an ultrasonic humidifier and shoots an image on it with a projector. Floating 3D content looks three-dimensional and the image is quite realistic. It has the disadvantage of being able to watch the picture properly when viewed from the front, and the need to have a device that generates water vapor, which means that water is always needed and can be seen only in a defined space, but it is not a way of blocking a space like a glass film or transparent film. In recent years, the use is increasing in the field of performances.

According to the present invention, a hologram screen is formed on a front surface of a projector or various projectors so that an image can be easily enjoyed by forming a screen on the front of a hologram without the inconvenience of having to install a projector, a bracket, a screen, or a projector lamp.

The purpose and possibilities of holograms

The easiest thing to see around is the hologram on your credit card. Credit cards have reflective holograms to prevent counterfeiting. 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 entire hologram can be reproduced with a small piece of hologram as if you were looking through the window. The information stored in the hologram is very resistant to contamination or damage and is superior in capacity to other storage media. Furthermore, if research on a method of reproducing continuous images is conducted, it is possible to produce a film using holograms, and it can be used for medical purposes since the human skeleton structure can be observed in three dimensions. In addition, it can be used in various fields such as architecture and automobile design.

There is a wide range of applications corresponding to the characteristics of holography. In addition, holography can form an image of a light source without using a lens, and many methods have been developed according to a method of illuminating a subject, a method of illuminating a reference light, and a light source or a photosensitive material.

It also has the function of multi-information processing that can record multiple images on one hologram and reproduce them all at once, and can reproduce stereoscopic images. will be possible, because when the reproduction in accordance with the needs of motion picture film set was converted to the hologram at any possible damage or dust selector vision without any of the film, look broiling a hologram recording in a short wavelength light to longer wavelength light different look enlarged X It is also possible to see the inside of a living body in three dimensions in the size of the body as -line microscopic holography .

The problem to be solved by the present invention is to make it easy to enjoy the image by being formed on the front of the hologram screen in the projector without the inconvenience of having to install a projection screen, a bracket, a screen, a projector lamp, and the like.
