Chapter 224 Natural Media
If there are people in the virtual reality industry around at this time, they may have guessed what they are talking about when they hear the media mentioned by the two, and then think of the main businesses of Mulong Technology and the trend of future technology. up.

That is, holographic projection!

The concept of holographic projection has been around for a long time, but it is well-known to the audience, mainly because science fiction movies often use this technology, not because holographic projection has entered our lives. In fact, real holographic projection can be found in The holographic projection formed in the air is still far away from us.

This statement may cause rebuttals. After all, when it comes to holographic projection, many people will definitely think of Hatsune Miku and the avatars at some concerts and galas in the past two years. However, that is not a holographic projection, but a Pepper's phantom. .

Pepper's illusion is a very clever optical illusion technology, but its principle is not complicated.The light shines on the real performer, and through the glass, it is reflected on a specific area on the stage to form a virtual image. This is the imaging process of Pepper's illusion.

Coupled with the increasingly mature CG technology and high-brightness lighting, the Pepper's Illusion show can be lifelike and lifelike.And it was falsely called holographic projection technology by related companies.After all, it has something to do with holography, it sounds amazing, doesn't it?

So what exactly is holographic projection?It is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of the object, and its realization 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 object to be photographed forms a diffuse object beam under laser irradiation; another part of the laser light is used as a reference beam to irradiate on the holographic film, and interferes with the object beam superposition, and converts the phase and amplitude of each point on the object light wave into a space The intensity of the change, so as to use the contrast and spacing between the interference fringes to record all the information of the light wave of the object.After the film with interference fringes is processed through developing, fixing and other processing procedures, it becomes a hologram, or a 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.The hologram is like a complex grating. Under the irradiation of coherent laser, the diffracted light wave of a sinusoidal hologram can give two images, namely the original image and the conjugate image.The reproduced image has a strong three-dimensional effect and has a real visual effect.Each part of the hologram records the optical information of each point on the object, so in principle, each part of it can reproduce the entire image of the original object, and multiple different images can be recorded on the same film through multiple exposures. And they can be displayed separately without interfering with each other.

If the comparison between holographic projection and Pepper's illusion is a bit abstract in principle, then we can simply conclude that holographic projection does not require any special medium to display images in the air above, and it will not affect clarity when viewed from any angle speed, and people can walk through the screen.

The Pepper's illusion is a visual effect formed by refracting light sources with optical materials tilted at various angles. The audience can only watch the movie at a specific angle, and it is impossible for people to pass through the screen.

But it is not a simple matter to form an image in the air without any special medium, at least there is still no complete solution at present, you must know how unstable and uncontrollable the air is something.

There are currently three mainstream solutions for holographic projection, which are relatively hopeful. One is the air projection and interactive technology invented by MIT graduate student Dyne, which can project interactive functions on the wall formed by the airflow. Image.This technology is derived from the principle of mirage, and the image is projected on the water vapor. Due to the uneven vibration of the molecules, it can form a layered and three-dimensional image.

The other is the 3D image projected by the laser beam. This technology was invented by the small island country. It mainly uses nitrogen and oxygen to spread out in the air. A transient 3D image is formed in theThis method is mainly realized by continuously carrying out small blasts in the air.

There is also a method called a 360-degree holographic display. This technology projects images on a high-speed rotating mirror to achieve a three-dimensional image. However, this method has been questioned because it does not get rid of the dependence on special media.

However, the first two methods have many problems in practical application, and the imaging effect is also very poor, and they are particularly unstable. They are still in the experimental stage, so 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 hero" wave algorithm has completed this mission.The characteristic of the wave algorithm is to dissect the law of particle movement through the motion of the wave. In fact, the original intention of the wave algorithm is to promote the development of quantum technology. Coincidentally, how to solve the problem of holographic projection, the most preferred theory of Wood Dragon Technology before is through quantum technology.

So when the previous research data was put into the wave algorithm, the wave algorithm successfully gave a realization method, that is, through special quantum equipment, changing the particle shape in the air within a certain range, so as to form a specific particle distribution as Holographic projections provide a suitable natural medium.

And in just 20 days, the guys in the virtual reality department have already produced a beta version of the quantum device!
This efficiency was so high that Liu Fan was a little shocked, "Everyone stayed up all night again."

"No one wants to leave." Liu Wei said with a gratified smile, "It's another technology that can change the world. Everyone wants to be a participant and witness. Everyone invested too much in holographic projection, and finally waited until this time. It's been a day.

Fortunately, the efforts have not been let down. If there is no long-term accumulation of research data, it is estimated that the wave algorithm may not necessarily come up with this answer. "

"Change the world," Liu Fan said to himself, then motioned Liu Wei to sit down, and told Liu Wei everything that Old Moore said.

"It really is Lao Mi's style." Liu Wei mocked, "What do you think now?"

"Use this major breakthrough in our algorithm as soon as possible. This battle must be responded to. We have no retreat, and we cannot choose to retreat. History tells us that cession of land and peace will not bring peace, but will become further aggression. Start."

"An all-out war may be a disaster, but it may also be an opportunity." Liu Wei took out a cigarette and said, "Chinese science and technology will eventually go through a test."

Liu Fan did not speak, and glanced at the tablet, "However, Old Moore reminded me that the fourth industrial revolution is indeed about to kick off. Taking advantage of this wave of war, the fourth industrial revolution , let us Huaxia start it."
