â— The nature principle of holographic projection technology phantom imaging
Holographic projection technology, also called virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce real three-dimensional images of objects.
The phantom imaging system is also called virtual imaging, which is based on the combination of "real scene modeling" and "phantom" optical imaging, and projects the captured images (people, objects) into the main model landscape in the scene box to demonstrate the development of the story. The sound is vivid, unpredictable, and very intuitive, leaving a deep impression. It is composed of three-dimensional model scene, modeling lighting system, optical imaging system (using phantom imaging film as imaging medium), film and television playback system, computer multimedia system, audio system and control system, which can realize large scenes, complex production lines and large products Lifelike display.
â— Phantom imaging analysis of holographic projection technology
Holographic technology is a technology that uses the principles of interference and diffraction to record and reproduce the light wavefront of an object. The first step is to record the light wave information of the object using the principle of interference, which is the shooting process: the object under the laser irradiation forms a diffuse object beam; another part of the laser is used as a reference beam to hit the holographic film, and the object beam is superimposed Interference occurs, converting the phase and amplitude of each point on the object light wave into a spatially varying intensity, thereby recording all the information of the object light wave using the contrast and spacing between the interference fringes. The negative film that records the interference fringes becomes a hologram, or hologram, after processing procedures such as development and fixing; the second step is to reproduce the light wave information of the object using the principle of diffraction. This is the imaging process: a hologram is like a hologram Complex gratings, under the irradiation of coherent laser light, a diffracted light wave of a linearly recorded sinusoidal hologram can generally give two images, namely the original image (also called the initial image) and the conjugate image. The reproduced image has a strong three-dimensional sense and has a real visual effect. Each part of the hologram records the light information of each point on the object, so in principle each part of it can reproduce the entire image of the original, and multiple different images can be recorded on the same negative film through multiple exposures. And can be displayed separately without disturbing each other. Using holographic projection technology, people in different places can communicate "face-to-face", which is amazing.
The single-sided phantom imaging system is based on the combination of "real scene modeling" and "phantom" optical imaging. It is vivid and unpredictable. It is very intuitive and gives a deep impression. It is composed of three-dimensional model scene, modeling lighting system, optical imaging system, film and television playback system, computer multimedia system, sound system and control system,
The phantom imaging system is based on the wide-screen environment, scene model and light transformation as the background, and then superimposes the captured live portraits into the scene to form a dynamic video screen. This phantom imaging technology, known internationally as "Fanta-View Magic Vision", uses the principle of optical illusion to combine the images (people, objects) captured in the movie with Musk camera technology and the main model landscape in the set box synthesis.
It is based on the combination of "real scene modeling" and "phantom" optical imaging to obtain the realistic effect of the combination and interaction of "phantom" and real scene modeling. The system is composed of three-dimensional model scene, modeling lighting system, optical imaging system, film and television playback system, computer multimedia system, sound system and control system. The use of advanced multimedia technology and computer control technology can realize the realistic display of large scenes, complex production lines, and large-scale products.
â— Application of holographic projection technology phantom imaging
The phantom imaging system, as the most modern imaging technology today, has been widely used in various fields of China's national economic production. Phantom imaging can reveal a phenomenon, demonstrate a law, explain a scientific principle, explain a story, establish a corporate image, introduce a product, analyze data curves, and some scenes that are not suitable for people to enter in dangerous environments.
Suitable for display occasions: such as urban planning exhibition halls, libraries, museums, science and technology museums, archives, entertainment halls, exhibitions, expositions, etc.
The application of holographic projection technology in dance beauty can not only produce a three-dimensional aerial illusion, but also enable the illusion to interact with the performer to complete the performance together and produce a shocking performance effect. From the use of holographic projection technology in the Disel fashion show catwalk, the beautiful holographic projection screen accompanied the model's steps to bring the audience to another world, as if the audience experienced a dual world of virtual and reality. Then to the use of holographic projection technology in the fantasy theater "Anime Master Norman", stage art and movie fragments have shown an extraordinary fusion in the same space, showing the audience the latest innovations in the world's multimedia art. The service and sales industries are most in need of a mass foundation, and it is king to maximize consumer appeal. The use of holographic projection technology in this regard has gathered people's attention from a new perspective and aroused consumers' desire for consumption. The ultimate goal of the exhibition industry is how to sell products, and how to maximize the attention of exhibitors has become a magic weapon for this industry. Aiming at the exhibition industry, a 360-degree virtual imaging system was launched in real time, which suspended three-dimensional images in mid-air imaging of the real scene, creating an atmosphere that is both illusory and true. The effect is unique and the sense of technology is full. Opened up a new marketing direction for the exhibition industry.
â— The difference between holographic projection and phantom imaging
A part of holographic projection during phantom imaging. The so-called holography means that 3D images can be seen at all angles, but none of the engineering applications currently seen can reach this level. In holographic projection, holographic films are currently used Planar imaging (using a translucent film to produce a small visual 3D effect), projection is direct projection imaging on the screen, phantom imaging can also be said to be a type of holographic imaging
The holographic projection should be directly projected in the virtual space without any imaging medium. Just like in Star Wars.
Phantom imaging is actually the reflection of the bottom or top image (the image can be a modified TV) by tilting the glass at an angle of 45 degrees (you can add a reflective film or use high reflective glass or transflective glass to improve the reflected picture effect) (The image displayed by the projector is also the screen projected by the projector).
In comparison, the technique of phantom imaging is much simpler.
