Movie black technology

"Quickly tell me about the principle of your holographic projection." The old principal greeted Chen Shen, and the two sat down on the stone benches resting on the roadside and asked with great interest.

As he spoke, he took out his glasses from his pocket and put them on so that he could see Chen Shen better.

Facing the eager eyes of the old principal, Chen Shen smiled and said the principle of the technology without worry.

"In fact, it's just a little trick, not an epoch-making technology."

He continued:

"At present, people's common holographic projection is generally to use holographic film to realize 3D image projection, and the holographic film must be hidden by the on-site light so as not to be discovered by the audience."

"My holographic projection principle is based on the principle of acoustic tweezers, that is, the technology of controlling the movement of small objects through sound waves. It controls thousands of tiny particles in the air to form a frame of objects that need to be imaged in the air. A special light is used to illuminate this frame to form a complete three-dimensional image."

The old principal listened, calculated it in his heart, and said in surprise: "This is not a trick you said!"

Let's not talk about how to use acoustic tweezers to control a large number of small particles, and let them form a specific shape, just talk about how to show the correct color after the light hits the frame formed by the particles. This is also a big project.

"Then how do you make the light show the correct color?" He hurriedly asked the doubt in his heart.

Chen Shen laughed: "Objects absorb light selectively. We can absorb specific light through the particles controlled by acoustic tweezers. Each type of particle absorbs light differently. In this way, we can control these particles. So as to control the color of the displayed image."

If there is no requirement for too bright colors for the displayed image, the holographic projector can even control the sparse dust in the air for projection.

In the beginning, the holographic projection in the mecha and the angular holographic projection came from this way. The image color of the two is relatively single, and there is no high demand.

The old principal opened his mouth and didn't know how to describe this technique.

Using acoustic tweezers to perform such delicate operations on particles is not only a problem with technical equipment, but also problems with programming and granular materials...

If he had not seen the holographic images exhibited at the Angular Press Conference, if the person sitting in front of him was not Chen Shen, he believed that the probability of this technique would be almost zero.

Chen Shen let the old principal slow down, and then discussed a few basic technical details with the old man.

Although the old principal didn't dabble in acoustics, he still knew some basic ideas.

Detailed and in-depth communication quickly dispelled his doubts.

It didn't take long for the two to talk about cooperation.

"Your current technology is very mature, there is no need to cooperate with us anymore." After listening to Chen Shen's remarks, the old principal has understood that this is a mature technology and does not require their school to blend in. .

This kind of cooperation is more like rubbing the results to brush up the results, and he will not allow such things to happen under his nose.

Chen Shen shook his head and said: "Your idea is too ideal. If this technology is fully mature, then I would have released this technology long ago."

He smiled bitterly and said: "This technology still has a big problem."

"First of all, the current machine can only control a thousand particles with acoustic tweezers. The image projected with them is not only limited in size, but also in color display and range."

"This is also the reason why the holographic images you saw before are all installed in the showcase, because a machine can only project such a large image."

The old principal asked: "Then why not connect them in series? So if each machine controls a thousand particles, it should be able to easily break the limit."

Chen Shen heard the old principal's simple thoughts, and suddenly felt that he had found a confidant.

However, it is not so easy to connect multiple projectors in series.

He replied: "At present, I can only achieve a series of less than five machines, but this can only achieve an image about the size of a human."

"The number of series goes up further, control programming is a very critical issue, and I am usually very busy."

Chen Shen smiled, and the old principal suddenly understood.

The programming mentioned here is more than just knocking on the computer and writing code.

In addition to computers, programmers must have a sufficient understanding of optics and acoustics before they can write good enough control programs.

This is the same as mecha, a proper interdisciplinary project.

The old principal nodded: "I understand."

"Hmm!" Chen Shen also nodded with a smile.

"Your kid just came back to school to find coolies!" The old principal was rude, and pierced him with a single sentence.

"Ahem!" Chen Shen stopped the old principal's words, "This is scientific research cooperation, school-enterprise cooperation, where is it to find coolies?"

The old principal smiled: "Then, as you said, treat it as a school-enterprise cooperation."

"I will ask the capable team in the school to see if they are willing to help you work."

"Thank you so much."

"Let's go, take you to the school cafeteria again?"

"Forget it, I have an appointment with someone." Chen Shen quickly left.

To be honest, after he got used to the delicious food in the base, his appetite was already whipped up, and he didn't want to try again.

"It's all right, go to work as soon as possible, and come back later if you have time."

The old principal waved, and the two separated here.

After Chen Shen got in the car, he drove directly to the hotel.

His parents are waiting for him there.

The car quickly drove into the hotel parking lot, and the guards beside him led him to his room.

And next to his room is his parents' room.

He knocked on the door, and my mother immediately came to open the door.

"Son, you are back!" The moment the door was opened, it was an excited hug.

"My son's birthday has just passed, so there is no need to be so passionate..." Dad said in the room.

"That's you ruthless! Your son has won such a big prize, you are not at all excited!" The mother rolled her eyes and said.

"How can this be ruthless? I'm not used to it. I didn't get excited for a while..."

"Alright, mom, have some fruit."

Chen Shen washed the fruit he bought on the road, put it on a plate and handed it to the old man.

There are no special products in the base to bring back, so I have to buy some fruits on the side of the road as my heart.

Of course Father Chen and Mother Chen didn't care about this. The son was already so arrogant, what else should he care about?
