Derivation technology of holographic imaging technology

With people gradually unsatisfying the visual effects brought by ordinary 3D stereo imaging, and the appearance of more research results of digital holographic technology and imaging media, a number of products using digital holographic technology came into being and were widely used in various industries.

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.

Front projection holographic display

Holography refers to a new photography technology, which records all the information of the amplitude and phase of the reflected wave of the object being photographed. Ordinary photography records the light intensity distribution on the surface of the object, but it can't record the phase information of the reflected light of the object, so it loses its three-dimensional sense.

Holographic projection can view different sides of the holographic image 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.

Fog screen stereo imaging

Fog screen stereoscopic imaging system Fog screen stereoscopic imaging is also called fog screen imaging, which uses laser to image in the air with the help of particles in the air, uses atomization equipment to create an artificial spray wall, uses this spray wall to replace the traditional projection screen, and combines aerodynamic principles to create a screen that can generate plane fog, and then projects the projector onto the spray wall to form a holographic image.
