Three-dimensional holographic imaging technology products

With people gradually dissatisfied with the visual effects brought by ordinary 3D stereo imaging, and more research results of digital holographic technology and imaging media appear, a number of products adopting digital holographic technology have emerged and are widely used in various industries.

1.360 holographic phantom imaging system

360 holographic imaging is a four-sided cone made of transparent materials. When the audience's line of sight passes through one face of the vertebral body, they can see the image of the free floating space in the vertebral body through the mirror and reflection.

The system consists of cabinet, spotlight, spectroscope and video player. Based on the principle of spectroscopic imaging, after the product is actually shot, the product image or three-dimensional model is superimposed on the scene, and the three-dimensional picture can be viewed without any auxiliary equipment. This product is mainly used to display detailed items, such as cars, jewelry, people and so on.

2. Holographic projection

Holographic projection is a very popular technology recently. It uses holographic film and projection to display products, provides rich holographic images, can be imaged on glass, acrylic and other materials, integrates decoration and practicality, and has become a cutting-edge marketing means. In 2008, CNN applied holographic projection technology to the report of the presidential election for the first time. It used 35 high-definition cameras to shoot the host from all angles at the same time, and the captured image data was transmitted to 20 computers for synthesis, and finally the holographic portrait was truly reproduced through hd projector.

Holographic projection technology is to form three-dimensional images on air or special lenses, which is an imaginary development of holography, and can view different sides of holographic images from any angle. At present, the reverse display of urban photography can be divided into three types:

(1) air projection: A 29-year-old graduate student in Massachusetts, USA, invented an air projection technology, which can project an image onto an airflow wall and make it interactive. Inspired by the mirage principle, this technology projects the image on a large piece of water vapor, which can form a holographic image with strong stereoscopic effect due to the uneven vibration of water molecules.

(2) Laser beam projection: Japanese companies have developed a holographic image projection method, which uses laser beams to project entities. This method mainly makes use of the fact that when oxygen and nitrogen diffuse in the air, their mixed gas becomes a hot substance, and a holographic image is formed through continuous small explosions in the air. (3) Researchers at the University of Southern California have developed a 360-degree holographic display screen, which projects images onto a high-speed rotating mirror to realize holographic images.

3. Fog screen stereo imaging system Fog screen stereo imaging, also known as fog screen imaging, is to use particles in the air to image in the air by laser, and use atomization equipment to generate artificial spray walls. This kind of water mist wall is used to replace the traditional projection screen, combined with aerodynamics to create a screen that can produce plane fog, and then projected onto the spray wall with a projector to form a holographic image.
