Technical products of 3d hologram technology

With people gradually not satisfied with the visual effect brought by ordinary 3D stereoscopic imaging, as well as the emergence of more digital holographic technology and the research results of the imaging medium, a number of products utilizing digital holographic technology have appeared, and have been widely used in various industries.

1.360 Holographic Phantom Imaging System

360 holographic imaging, is a four-sided cone made of transparent material. When the viewer's line of sight passes through one of the faces of the vertebrae, it is able to see a free-floating image from the space inside the vertebrae through surface mirroring and reflection.

This system consists of cabinets, spotlights, spectroscopes, video players and other components, the use of spectroscopy imaging principle, the product of the actual three-dimensional modeling will be superimposed on the product image or three-dimensional model into the scene, without any auxiliary equipment to watch the three-dimensional picture. This product is mainly used to display items with rich details, such as automobiles, jewelry, and characters.

2. Holographic projection

Holographic projection is a very popular technology in the near future, it uses a holographic film with the projection of display products, providing a rich holographic image, can be imaged on glass, acrylic and other materials, decorative, practical into one, and has become a cutting-edge means of marketing. 2008, the United States for the first time in the presidential election coverage of CNN television station, applied the holographic projection technology. Application of holographic projection technology, the use of 35 high-definition cameras, from all angles at the same time on the host of the shooting, shooting image data transmitted to 20 computers in the synthesis process, and ultimately through the high-definition projector to achieve a holographic portrait of the real reproduction.

Holographic projection technology is through the air or special lenses to form a three-dimensional image, is the holographic photography of the proposed development, can be viewed from any angle of the holographic image of different sides. Currently the city of photography of the reverse display, the field can be realized on the holographic projection from the technology is divided into three kinds:

(1) air projection: the United States of Massachusetts, a 29-year-old graduate student invented a kind of air projection) technology, can be projected on the wall of the airflow image, and make it have an interactive function. Inspired by the mirage principle, the technique projects an image onto a large area of water vapor, creating a three-dimensional holographic image due to the uneven vibration of the water molecules that make up the vapor.

(2) laser beam projection: the Japanese company developed a use of laser beams to project the entity of the holographic image projection method. This method mainly utilizes the oxygen and nitrogen in the air when dispersed, the two mixed into a gas into a burning substance, and in the air through constant small explosions to form a holographic image. (3) Researchers at the University of Southern California in the United States have developed a 360-degree holographic display: a holographic image is realized by projecting the image onto a high-speed rotating mirror.

3. Fog screen stereoscopic imaging system fog screen stereoscopic imaging, also known as fog screen imaging, through the laser light with the help of particles in the air, imaging in the air, the use of fogging equipment to produce an artificial spray wall, the use of this layer of water mist wall instead of the traditional projection screen, combined with aerodynamics to create a screen that can produce a plane of fog, and then the projector will be projected on the spray wall to form a holographic image.
