Movie black technology

"Tell me about the principle of your holographic projection in detail." The old headmaster greeted Chen Shen, and the two sat down on the stone bench resting on the side of the road, asking questions with great interest.

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

Facing the old headmaster's thirsty eyes, Chen Shen smiled and explained the principles of the technology without any worries.

"Actually, it's just a trick, not an epoch-making technology."

He continued:

"At present, the common holographic projection is to use holographic film to realize 3D image projection, and the holographic film must be hidden by on-site lighting so that it cannot be discovered by the audience."

"The principle of my holographic projection is to use the principle of acoustic tweezers, that is, the technology of controlling the movement of small objects through sound waves, to control thousands of tiny particles in the air, so that they can form an object frame in the air that needs to be imaged. Illuminate this frame with special light at different angles to form a complete three-dimensional image."

After hearing this, the old headmaster thought about it, and said in surprise, "This is not some trick you said!"

Not to mention how to use acoustic tweezers to control a large number of small particles and make them form a specific shape, but how to display the correct color after the light hits the frame formed by the particles 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 said with a smile: "The absorption of light by objects is selective. We can absorb specific light through the particles controlled by acoustic tweezers. Each particle absorbs light differently. In this way, we can This controls the color of the displayed image."

If there are not too bright color requirements for displaying images, the holographic projector can even control the rare dust in the air for projection.

In the beginning, the holographic projection in the mech and the holographic projection of the corners came from this way. The color of the two images is relatively single, and there is no high demand for them.

The old headmaster opened his mouth, not knowing how to describe this technique.

Implementing such a fine manipulation of particles through acoustic tweezers is not only a problem of technical equipment, but also a problem of programming, particle materials...

If he hadn't seen the holographic images exhibited at the corner conference, and if the person sitting in front of him was not Chen Shen, he believed that the probability of this technology was almost zero.

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

Although the old headmaster didn't have much experience in acoustics, he still has a general understanding of some basic assumptions.

The detailed and in-depth communication soon completely 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 narration, the old principal already understood that this is a mature technology, and there is no need for their school to mix it up .

This kind of cooperation is more like trying to rub the results to brush up the results. He will not allow such a thing 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 a long time ago."

He said with a wry smile: "There are still big problems with this technology."

"First of all, the current machine can only control a thousand particles through acoustic tweezers, and the images projected by them are not only limited in size, but also in color display and range are greatly limited."

"That's why the holograms you saw before were all placed in display cabinets, because a machine can only project so large an image."

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

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

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

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

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

Chen Shen smiled, and the old principal immediately understood.

The programming mentioned here is not just tapping the computer and writing code.

In addition to computers, programmers must also have sufficient understanding of optics and acoustics, so that it is possible to write a good enough control program.

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

The old headmaster nodded: "I understand."

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

"You kid just came back to school to look for coolies!" The old headmaster was unceremonious, and pointed him out in one sentence.

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

The old headmaster chuckled: "Then, as you said, consider it 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 eat in the school cafeteria again?"

"Forget it, I've made an appointment with someone else." Chen Shen hurriedly said goodbye.

To be honest, after getting used to the delicious food in the base, his appetite has been whetted, so he doesn't want to try it again.

"Okay, okay, hurry up and get busy if you have something to do, and come back later when you have time."

The old principal waved his hand, and the two parted here.

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

His parents were there waiting for him.

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

And next door 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, there was an excited hug.

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

"That's because you are ruthless! Your son has already won such a big award, and you are not excited at all!" Mom said rolling her eyes.

"Why is this ruthless? I'm used to it, so I didn't get excited for a while..."

"Okay, mom, let's eat some fruit."

Chen Shen washed the fruits bought on the road, put them on a plate and handed them to the second elder.

There are no special products in the base that can be brought back, so I had to buy some fruit on the roadside as a gift.

Of course, Chen's father and Chen's mother didn't care about it. The son was already so competitive, so what else should he care about?
