"3D holographic projection is a kind of real three-dimensional image of an object that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of the object, and it is a real-life 3D technology that does not require glasses, and the audience can see a three-dimensional virtual character.

We all know that in order for people to see three-dimensional 3D images with the naked eye, there must be a reflective medium. Water vapor in the air can be used, air can be used, and a transparent 3D imaging film can be used.

I prefer to use the water vapor in the air, water vapor is ubiquitous, and there is no need to set up a special scene, for example, the 3D imaging film must be specially arranged, which cannot be used anytime and anywhere, which is not very convenient.

Using the laser beam as the projection medium, the laser is irradiated into the air, causing the water vapor in the air to oscillate, so as to realize the function of reflecting the image.

Each beam of light of the laser beam represents every point of light on the image that needs to be projected, because the water vapor in the air is three-dimensional transparent, we use this feature to control each beam of light of the laser beam to irradiate the water vapor at different distances, so as to produce a three-dimensional 3D image.

When we take pictures, the subject is originally three-dimensional, but due to the display screen, the three-dimensional image cannot be restored. So can we assume that there is also stereoscopic information on the plane image?

Then we summarize this stereo information and divide the diagram into N light points, which represent each stereo point on the real object.

After obtaining this stereo image data, we divide the laser beam into N micro beams, which represent each light point in the stereo image data and set different projection distances. So this laser beam irradiates the water vapor in the air, causing the water vapor in different positions to vibrate and reflect, and it becomes a 3D stereoscopic image?

It's just my assumption, let's see if it makes sense. But I can tell you for sure that 3D holographic projection technology will definitely be realized in the future. So if you do it now, it's a testament to how much more advanced our 3D holographic projection technology is decades ahead of other companies. ”

"Bang bang!" Shen Danqing finished speaking, and there was warm applause in the conference room. The boss has come up with a black technology idea again, 3D holographic projection technology! They have never heard of it, and it is the first time they have heard the boss say, it seems to be very reasonable, and it seems that it is not difficult to do all this. You know, the thinnest laser beam they can do is already in the nanometer range. It is enough to correspond to each point of light, and the stereo image will be very detailed. It's also easy to control the throw distance, but the difficulty is to make each laser beam have a different color, and the company doesn't have this technology yet, so they need to study it.

The laser technology is in charge of the Institute of Physics, so Hu Weihong stood up and said: "Boss, there is no other problem, but we have not yet achieved that every nano laser beam emits any color of light." We need to study this, and we may not be able to do it in a short time!"

"If not, just emit a green light. Shen Danqing replied. It is really difficult to make such a small LED laser projector emit any color of light, which even later generations have not done, so Shen Danqing did not force it.

"Hey, we'll do our best to look into it. Hu Wei replied in a firm tone.

Shen Danqing nodded, and then said to everyone in the conference room: "If you don't have other difficulties, then dismiss the meeting! ”

After saying this, Shen Danqing took the lead in leaving the conference room.

Back in the office, he sat down on the recliner and thought about it, to see if there was anything he hadn't recalled, not to mention, he really thought of two very practical devices. Considering that Guo Dong was a busy man and had no time, he decided to go to Changsheng Seiko to find him in person.

He's a man of action, he just does what he says. He got up and walked outside and said to Secretary Liu: "Secretary Liu, come with me to Changsheng Seiko." ”

"Hey!" Secretary Liu answered, and immediately got up and walked with him. He knew that the boss was an impatient person, and he would leave as soon as he said he would, so he acted quickly, and after so many years of secretary, he already knew the boss's personality well.

When I arrived at Changsheng Seiko, I found him in the experimental workshop. When Guo Dong saw Shen Danqing, he happily greeted him first: "Boss, you came just in time, there are several power systems that can already be practical." ”

"Hehe!" Shen Danqing smiled when he heard the good news, and he asked excitedly, "Which power system is it?"

"I've heard you say before that there are a few cars that are in a hurry to make movies and make props, so I deliberately accelerated the development of several powertrains. They are available in 0.9-liter, 1.6-liter, 3.0-liter, and 4.2-liter engines with an AMT automatic manual transmission. ”

"Great, I just need these powertrains. We are about to shoot a smart life commercial, and we urgently need a few prop cars, Dean Guo, you have made a great contribution. Shen Danqing said to Guo Dong with a smile.

"The boss has won the prize, this is what I should do. Guo Dong said modestly.

"Dean Guo, then hurry up and assemble a few prototypes, and I'll come and see them then." However, I'm not here today for this, I thought of two products that are easy to make money, and our smart life advertising film also needs these two props. ......" Shen Danqing explained his intentions, and was about to explain, but was interrupted by Guo Dong: "Boss, you wait, wait until I take a pen and paper to remember." ”

Boss, don't look at the books, but his ideas are all golden ideas, which have been proven countless times in the past, Guo Dong attaches great importance to it, he is afraid that he will forget, so he wants to find a paper to write it down.

"Well, go ahead! I'll wait for you. Shen Danqing was very satisfied with Guo Dong's attitude, so his tone was very gentle. The smile on his face is like Bole has fallen in love with a thousand-mile horse.

After a few minutes, after Guo Dong found a pen and paper, squatted on the ground, and lay on his knees to get ready, Shen Danqing said while recalling: "There are two technological products, the first one I call a balance scooter, or it can be called a balance bike." Balance and mobility are the hallmarks of this car. Using a high-energy iron lithium-ion battery as a power source, two wheels with a diameter of about 10 to 15 centimeters, with hub motors on the wheels, rare earth permanent magnet DC brushless motors, gyroscopes to control the balance of the car body, and the use of non-bearing rocker arm shock absorption technology on the car, the two wheels can be moved to steer, but instead of a steering wheel, but an electronic signal to control the steering.

The specific method is that when a person stands on the pedal, there is a gravity sensor under the pedal, if the left foot is forced, that is, the weight of the body is pressed on the left foot, the wheel will turn to the left according to this signal, and the same principle is to turn to the right, if the right toe is forcefully indicating forward, the toe of both feet is forcefully indicating stopping, and the left heel is forcefully indicating backwards. Pressing on the right heel indicates acceleration.

This is just my personal opinion, and you can also change my settings according to the actual situation.

Since it is a scooter, the pedal is not high, about six or seven centimeters high. It is convenient for users to get on and off the bus. The two wheels are on both sides of the pedal, and the upper edge should be wrapped to prevent safety accidents. By the way, the tires should be pneumatic tires without liners, so that the shock absorption performance will be better.

Dean Guo, do you understand what I mean?"

Guo Dong took notes before replying: "Boss, I understand, this shouldn't be difficult for us, a lot of it is technology in cars." ”

"Well, if you're sure. The second product may be a little more difficult, it is a small intelligent unmanned aircraft, which is very small and very light. It is mainly used for photography and photography, and can also be used for short-distance delivery in the future, which is relatively small and lightweight. That needs the support of positioning technology, so we'll leave him alone for now.

Let me talk about my idea, its power source is also a high-energy lithium-ion battery, a square, on the four corners of the square, there is a micro motor driven by engineering plastic propellers, it is these four propellers to generate lift and kinetic energy.

Four micro-motors, each mounted on top of two crossed telescopic booms. This is mainly easy to carry,

If the lift is not enough, you can also design six micro motors, not certainly. That's just my word for it.

The key to the problem is to be light, in addition to the performance of micro motors and plastic propellers is also very important, and this aircraft is not a simple remote control aircraft, but an intelligent drone, it has a built-in electronic map, which needs the support of wireless positioning technology. The user can also control it remotely using the control program.

Of course, since there is no mobile network and mobile positioning technology, you should first make a remote control plane. This kind of product will not be sold for the time being, so you will make a few movies and commercials.

By the way, it also has a built-in electronic gyroscope that allows it to keep its balance stable, and you know that photography is the most shaky, so it's important to keep it stable.

I'm done, Dean Guo, have you figured it out?"

Guo Dong took notes, stood up and said: "Boss, I fully understand the meaning of this unmanned aircraft, from the perspective of mechanical technology alone, there is no difficulty, but it has been applied to a lot of electronic technology and software technology, which I am not familiar with, I have to discuss with Hong Tao and Lu Rucheng to know whether it can be done or not." ”

"Okay! You understand, you go and discuss with them before talking! Also, step up the assembly of the spring C1, spring Ruichi, Tang Dynasty A6 three cars, it is best to assemble more, so that it is more convenient to experiment. Shen Danqing said to Guo Dong with a smile.

Then he shook his hand and said hello, and turned his head away, he was so happy that he got carried away, thinking that he would soon be able to get into the company's car, his whole body was strong, so he walked fast, and within a few minutes he arrived at the parking place.

"Go back to the company" and get into the car, he instructed Secretary Liu. Then he reclined down in his seat and thought about the good things.
