Introduction
Holographic projection technology is a high-tech technology that has emerged in recent years. It is a three-dimensional image that records and reproduces objects using the principles of interference and diffraction. It is changing the aesthetic attitude of the traditional stage acoustic and optoelectronic technology with a new kind of thing. This holographic projection technology is based on the times and is widely used in all aspects of society.
As shown in the figure, this is a high-end hotel in the United Kingdom that uses holographic projection technology to guide the occupants to the designated room. The vivid space on the screen is vividly colored, with high contrast and sharpness, and a sense of space and perspective. This technology creates a dual world of virtuality and reality with sci-fi effects.
principle
Holographic technology is a technique for recording and reproducing the recording and reproduction of a true three-dimensional image of an object using the principles of interference and diffraction.
The first step is to record the light wave information of the object by using the interference principle. This is the shooting process: the object forms a diffuse object beam under laser irradiation; the other part of the laser beam is used as a reference beam to the holographic film, and the object beam is superimposed. Interference is generated to convert the phase and amplitude of each point on the object's 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. After the film on which the interference fringes are recorded is subjected to processing procedures such as development and fixing, it becomes a hologram, or hologram;
The second step is to use the principle of diffraction to reproduce the light wave information of the object. This is the imaging process: the hologram is like a complex grating. Under the coherent laser illumination, the diffracted light wave of a linearly recorded sinusoidal hologram can generally give two The image, the original image (also known as the initial image) and the conjugate image. The reproduced image has a strong stereoscopic effect 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 film by multiple exposures. And they can be displayed separately without interference. Domestic comparisons include Tsinghua University, China Science and Technology, China Optoelectronics Research Institute, Zhejiang University, National University of Defense Technology, Shanghai Jiaotong University, Jiangsu University, etc. In addition to optical holography, infrared, microwave and ultrasonic holographic techniques have been developed. These holographic techniques are of great significance in military reconnaissance and surveillance.
application
The application of holographic projection technology in the dance beauty can not only produce a three-dimensional aerial illusion, but also enable the illusion to interact with the performers and complete the performance together to produce a shocking performance. From the use of holographic projection technology in the Disel fashion release T-stage show, the beautiful holographic projection screen with the model walks the audience to another world, as if the audience experienced a virtual world of reality and reality. Then, in the use of holographic projection technology in the fantasy theater "Anime Master Norman", stage art and film fragments have an extraordinary fusion in the same space, showing the audience the latest innovations in the world of multimedia art. The service and sales industry is the most in need of masses, and it is king to maximize consumers. The use of holographic projection technology in this area brings people's attention to a new perspective, which evokes consumers' desire for consumption.
The ultimate goal of the exhibition industry is how to sell the products, and how to maximize the attention of the participants has become a magic weapon for the industry. For the exhibition industry, the 360-degree phantom imaging system was launched in real time, and the three-dimensional image was suspended in the mid-air imaging of the real scene, creating an atmosphere of illusion and trueness, with peculiar effects and full of science and technology. Opening up new marketing directions for the exhibition industry.
prospect
The holographic projection technology breaks through the limitations of traditional sound, light and electricity, bringing beautiful pictures to the audience, giving people a double world feeling of coexistence of reality and reality. The method of holography has been extended from the field of optics to other fields. Such as microwave holography, acoustic holography, etc. have been greatly developed, successfully applied in industrial medicine and other aspects. Holographic waves, electron waves, X-rays, etc. are also being studied in depth. Holograms have an extremely wide range of applications. For example, the shock wave used to study rocket flight, the non-destructive testing of aircraft wing honeycomb structure, etc., the future development potential of holographic projection technology market will be incalculable.
The DMX console is the central controller for controlling all stage lights and special effects equipment. Almost all equipment needs to be connected to it, and users use it to issue control commands to all equipment. It can be controlled in real time, or the device can be programmed to display specific effects at a fixed time. Even with the stage equipment, the DMX console is also essential, just like there are more soldiers, the commander still needs to give orders to them. There are also many different types controllers to work for different quantity Stage Lights.
