Chapter 226: Natural medium

If at this time there are people in the virtual reality industry on the side, hear the media mentioned by the two, and then think of the main business of Mulong Technology and the trend of future technology, maybe they have already guessed what they are talking about Already.
That is, holographic projection!
The concept of holographic projection has been around for a long time, but he is well known by the audience, mainly because science fiction movies often use this technology, not because holographic projection has already entered our lives. In fact, true holographic projection can be used in The holographic projections formed in the air are far from us.
This statement may cause rebuttal. After all, when it comes to holographic projection, many people will definitely think of Hatsune Miku and the virtual images of some concerts and evening parties in the past two years. However, that is not actually a holographic projection, but a Pebel illusion. .
Pebble illusion is a very clever optical illusion technique, but its principle is not complicated. The light shines on the real performer, and a specific area on the stage is mapped through the glass to form a virtual image. This is the imaging process of the Pebel illusion.
Coupled with the now more mature CG technology and high-brightness lights, Pepper's illusion performance can be lifelike and exquisite. And it is lied by related companies as holographic projection technology. After all, it has something to do with holography, it sounds terrible, no.
So what exactly is a true holographic projection? It is a technology that uses the principles of interference and diffraction to record and reproduce a true three-dimensional image of an object. Its implementation is divided into two steps.
The first step is to use the principle of interference to record the light wave information of the object, that is, the shooting process. The subject forms a diffuse object beam under laser irradiation; another part of the laser light is incident on the holographic film as a reference beam, and it superimposes the object beam to generate interference, which converts the phase and amplitude of each point on the object ’s light wave into space. The intensity of the change, so that all the information about the light wave of the object is recorded using the contrast and interval between the interference fringes. After the negative film recorded with the interference fringes undergoes 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, which is the imaging process. A hologram is like a complex grating. Under the illumination of a coherent laser, the diffracted light waves of a sinusoidal hologram can give two images, namely the original 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 object. Multiple exposures can also record multiple different images on the same film. And can be displayed separately without interference.
If comparing the holographic projection and the Pebel illusion in principle is a bit abstract, then we can simply conclude that the holographic projection does not require any special medium to display the image in the air above, and viewing from any angle will not affect the clarity Degrees, and people can walk through the picture.
The Pebel illusion is a visual effect formed by refracting the light source with optical materials inclined at various angles. The audience can only watch the movie at a specific angle, and it is impossible for people to pass through the picture.
But wanting to form an image in the air without any special medium is not a simple matter. At least there is no complete solution at this time. You must know how unstable and uncontrollable the air is. Something.
There are currently three mainstream solutions for holographic projection, which can give people a little hope. One is the air projection and interaction technology invented by MIT graduate student Dyne, which can project interactive functions on the wall formed by airflow. Image. This technology is based on the principle of mirage. It projects the image on the water vapor. Because the molecular vibration is not balanced, it can form an image with strong layers and three-dimensional effect.
The other is a 3D image of a laser beam projecting the entity. This technology was invented by the small island nation. It mainly uses nitrogen and oxygen to diffuse in the air. The mixed gas becomes a hot slurry and is in the air. To form a short 3D image. This method is mainly achieved by continuous small blasting in the air.
Another method is called a 360-degree holographic display. This technology is to project an image on a high-speed rotating mirror to achieve a three-dimensional image, but this method is questioned because it does not get rid of its dependence on special media.
However, the first two methods have many problems in practical application, the imaging effect is very poor, and they are particularly unstable. They are still in the experimental stage. Therefore, the most important thing to truly realize holographic projection is to find a suitable natural medium. "Out of thin air" imaging becomes a reality.
And this time the "big heroes" wave algorithm completed this mission. The characteristic of the wave algorithm is to dissect the laws of particle movement through the wave's motion shape. In fact, the original intention of the wave algorithm is to promote the development of quantum technology. Coincidentally, how to solve the mind problem of holographic projection is the most inclined theory of Mulong Technology before. Through quantum technology.
So when the previous research data was put into the wave algorithm ~ EbookFREE.me ~ the wave algorithm successfully gave an implementation method, which is to change the particle morphology in a certain range of air through special quantum equipment, so that The formation of a specific particle distribution provides a suitable natural medium for holographic projection.
And in just 20 days, the guys in the virtual reality department have already made the beta version of the quantum device!
This efficiency was so high that Liu Fan was a little shocked, "Let's stay up all night again."
"No one wants to leave." Liu Weixin smiled comfortably. "It is another technology that can change the world. Everyone wants to be a participant and a witness. For the holographic projection, everyone invested too much, and finally waited for this. It's been a day.
Fortunately, the efforts have not been disappointed. If there is no long-term research data accumulation, it is estimated that the wave algorithm will not necessarily reach this answer. "
"Well, change the world ..." Liu Fan said to himself, then motioned to Liu Wei to sit down, and told Liu Wei what Lao Moore said.
"It really is Lao Mi's style." Liu Wei mocked. "What do you think now?"
"As soon as possible, we will apply this major breakthrough in our algorithm. This battle must be responded to. We have no retreat and we cannot choose to retreat. History tells us that peace cannot be exchanged for peace, but it will become further aggression. s begin."
"A full-scale war may be a disaster or an opportunity." Liu Wei took out a cigarette. "Huaxia Science and Technology will endure a test."
Liu Fan did not speak, and glanced at the tablet. "But there is a word from Old Moore that reminded me that the fourth industrial revolution is almost time to start. It is the fourth industrial revolution in this wave of war. Let ’s start it with us ...
