Sorrento said to the man: This is just your holographic projection.
There have been countless people who have counted the VR devices in the "Top Player", so today I don't talk about VR, but to talk to you about the holographic projections in the movie. Holographic projections appeared as early as 1947, but they have only appeared in the public's field of vision in recent years, but the debate about holographic projections is a pseudo-holographic continuation. Today, we will listen to the technical director of Mengyun Holography.
ARC: Is there an article saying that holograms are now pseudo holograms? As a few listed companies in the industry, can we give us authority to explain?
Deng Tianci: This explanation is not correct. In the true sense, holographic technology is commercially expensive, and the principle of holography is applicable to various forms of fluctuations such as X-rays, microwaves, sound waves, and electron waves. At present, the most commonly used light source is a projector, because the brightness of the light source is relatively stable, and the projector also has the function of magnifying the image, which is very practical as a hologram display. So in commercial applications we will achieve holographic effects with the lowest cost and different technologies. The true holographic convention is a next-generation display technique that projects a three-dimensional image in three dimensions (the image is a physical "stereo" rather than a purely visual "stereo"). The existing holographic technology is a technical solution that is biased towards practicality. From a technical point of view, it is our company's focus to overcome the application of holographic technology similar to the film Iron Man without any medium in the air.
ARC: Your home is already on the market. Can this prove that the profit margin of holographic projection is relatively large? In fact, the cost of holography is quite expensive, so how do you achieve higher profits?
Deng Tianci: The application of the holographic technology industry has been extensive. The demand in all walks of life is different. In the whole process, we are relatively controllable to the profit space.
Different from the industry, the finished products that customers finally get have higher commercial value than the cost of our products. And in the process of the project to do the appropriate pre-sale, sale, after-sales service is our core concept. Therefore, the project can achieve a considerable premium space.
It is our company's mission to get high profits with professional services and innovative content to make customers value for money.
ARC: Your home currently holds 265 technical patents, but it has only been established for two years. On average, there is a new patent in less than three days. This speed is incredible. Have you dug a lot of talents at the beginning of the establishment?
Deng Tianci: In fact, the number of patents is continuing to increase. We have always valued the patent copyright, and the talent pool has always been at the forefront of the industry.
ARC: Can you give us the principle of holographic projection? What technologies does it cover?
Deng Tianci: Holography means that in addition to the frequency (color) and amplitude (brightness) of light, the phase information of the light field is retained.
Popularly speaking, a hologram is different from a normal photo, and it is deep. It records the interference fringes of the reference light and the reflected light from the recorded object. This stripe is not like a line on paper, but a knife-like scratch on the jelly. Therefore, the shooting of holograms usually requires a long exposure. After the exposure is completed, the film (dry plate) of the interference path between the reflected light and the reference light is recorded. At this time, as long as the reference light is irradiated from the original angle to the dry plate (or holographic film), the reference light rays pass through the dry plate. Time passes through the recorded interference route. At this time, the observer can observe the holographic image at the corresponding position from different angles, which is very stereoscopic.
Holographic projection, there must be a holographic film, the angle of observation must also be seen in the holographic film. The pyramid-shaped so-called holographic film that you usually see is just a plain plastic paper, a plane image that is emitted by the principle of reflection. There is a name called Pepper's illusion, and the three-dimensional sense is brain filling.
There is also a kind of air projection, which uses water mist to project. The video source is also flat, but the water mist is moving, so it has a level, its level is uncontrollable, and the stereo effect is also brain-filled.
ARC: Is the current application of holography mainly for performances? There are some holographic projections for concerts. What is the cost?
Deng Tianci: The application of holography is now very diverse, from a commercial perspective. Exhibitions, conferences, investment conferences, etc. have begun to use holographic technology to enhance the public's visual experience. The visual enjoyment of the public has slowly shifted from the traditional flat 2D to the naked eye 3D.
The holographic concert uses the very mature phantom imaging system on the market. The cost is still confirmed according to the actual situation of the site (area, environment, light, etc.).
ARC: At what stage is holographic technology currently developed, what new breakthroughs will be made in the future?
Deng Tianci: Holographic projection technology was first produced in the 1940s. After 1960, the emergence of laser made holographic projection technology enter a new stage. With the in-depth development of technology, transmissive holography, reflective holography, image holography, rainbow holography, synthetic holography, molded holography, digital holography and other technologies have emerged. At present, holographic projection technology has gradually matured and successfully applied in the fields of medicine, engineering, and visual arts.
Nowadays, holographic projection technology is applied more and more in stage effects and literary creation. A three-dimensional, purely optical space can convey image information that cannot be conveyed on traditional media. For example, in 2011, Zhuhai Yangshi Network Animation Design Co., Ltd. filed a patent application “3D holographic digital stage systemâ€, which created a multi-layered holographic screen in front of the stage background to create a dream effect that cannot be achieved by the traditional stage. In addition, holographic imaging technology is becoming more and more widely used in life services, medical applications, and military fields.
Litecoin (LTC) is a cryptocurrency created as a fork of Bitcoin in 2011. It uses a hashing algorithm called Scrypt that requires specifically designed mining software and hardware. It is minable, and continues to rank in the top cryptocurrencies for value and trading volume.
Litecoin mining is the process of validating transactions in the blockchain, closing the block, and opening a new one. Litecoin uses the proof-of-work consensus mechanism, which uses computational power to solve the nonce, which is part of the hash, that secures the block. The hash is the alphanumeric sequence of numbers that is encrypted by the hashing algorithm. When the nonce is solved, Litecoin is rewarded.
Litecoin mining became popular in 2011 when Charlie Lee, a software engineer at Google, announced its creation as a Bitcoin fork with modifications intended to help it scale more effectively.
Just like Bitcoin, it can be mined on computers using central processing units and graphics processing units. However, it isn't as profitable or competitive as purchasing an application-specific integrated circuit (ASIC) and joining a mining pool.
