"The biggest difference is that the active type requires itself to emit infrared rays to illuminate the object, and then use the lens on the light sight system to capture the infrared rays reflected from the object. This is also the infrared night vision instrument studied by various countries in the earliest period. Since a system connecting the anode and the cathode is used to accelerate electrons, there is a fatal problem with this method. The acceleration of electrons will distort the image formed by the infrared rays, and it will greatly reduce the life of the pipeline... At present, countries have long eliminated this technology. Moreover, this technology is also the technology used in our scopes at present, so comrades from Factory 298 need to solve this problem!" Qin Huaibao cannot remember all of the words Liu Yijiu said and guaranteed not to forget them.

So, after arriving in the design room, Liu Yijiu walked back and forth with his hands behind his back and forth, and he was sitting there recording quickly.

Liu Yijiu's speaking speed is very slow, which makes it easier for him to record.

"So, the night vision device we want this time and the scope with night vision function are to require them to use the passive infrared imaging technology that is being studied now. Or this technology can also be called a low light imager. There is a key core component like an enhancer. That is, through the faint moonlight and the ambient light emitted by the starlight to amplify the reflected infrared rays around it. This still requires the image enhancement tube technology. Since the positive electrode and cathode are still connected, there will still be image distortion and the problem of short pipeline life. At the same time, on cloudy and moonless nights, the visual distance will become very short. In the practical battle in the Northeast, they tell us that in the dark forest without light, their technology is garbage!" Liu Yijiu gritted his teeth and spitted out this word.

Qin Huaibao was stunned, "Master. Can't you say this? What if they think we don't respect their technology and cherish their achievements. We won't help us?"

If that's the case, you may be beaten to death by those old guys.

You can doubt anything, but you can't doubt their technology.

Qin Huaibao has been in Factory 298 for quite some time.

"Just say that, if you dare to use other words, then you will never think that you have a chance in these things. Although I am still a small corpse, I still have the right to do this." Liu Yijiu threatened Qin Huaibao. If they don't irritate these old men, they will be able to hold their tails to the sky.

If Liu Yijiu had not had some knowledge in these aspects last time, he shocked them so hard. God knows whether they would take Liu Yijiu seriously.

"And, you don't have to take any responsibility. You can't know much about these things. People have known what level you have had for so long. They know that I said..."

Qin Huaibao smiled bitterly on his face, but he was very depressed. They did know that it was you who said it, but you were too far away, and this was spit out of their mouths. If they lose their minds, take off their anger and beat themselves up to be unable to take care of themselves, it will be a lot of thanks!

"Continue to write! The new night vision instrument must have the ability to generate images under extremely weak light conditions. For example, the ability to generate images on a night without the moon is required. The sensitivity needs to be higher. To achieve this, you can attach a microchannel board to the image enhancement tube. I have already drawn the structure in this drawing, how to achieve it. This is their business, otherwise they will not need scientific research funds. The microchannel board MCP is made of high-resistance materials. The purpose is to increase the number of electrons and give up the acceleration of the original electrons. The degree of image distortion must be reduced to an acceptable range. At the same time, the brightness of the final image needs to be increased..." Liu Yijiu recalled while asking Qin Huaibao to write.

From time to time, I check if this guy has logged errors.

Qin Huaibao has given up on the idea of ​​understanding these things now. These things are not understandable by his IQ.

"Have you recorded it all?" Liu Yijiu asked to see Qin Huaibao stop writing.

"Yeah!" Can't you record it?

It is obviously not possible to lean on his head. Fortunately, he proposed to record with a pen, otherwise, when he got there, he really didn't know how to explain these things.

He didn't know that it was very difficult for Liu Yijiu to recall these things, because he didn't study this much at the beginning.

If it weren't for their experiments, the mice who were experimenting through genetic modification and had the ability to remember everything they could remember, the things they recorded would be left in their minds. When they needed to use them later, they could find most of the content with just a computer, relying on some keywords. Liu Yijiu was also stunned.

After all, any weapon design is a huge system and requires many aspects to be involved, so they must have super memory.

No one knows how much a person's brain can remember. After all, human research on the brain is only in its infancy.

"These things are theoretical things. After you write them down, you can remember them well. At that time, you have to say a few words and look at this book and the people who threw them into our base. Now, let's talk about this structural schematic..." Liu Yijiu did not check whether Qin Huaibao made any mistakes.

As long as you remember some key things, the other party will know.

They are experts in this area.

After saying that, he began to place the structural schematic diagram of the night vision device he designed on the table in front of Qin Huaibao.

This is a sketch, which is skewed and the annotations on it are extremely simple and not unstandard at all.

Fortunately, Qin Huaibao was able to get to know him.

"Sleepy? If you are sleepy, let's take a rest first." Seeing Qin Huaibao's two eyelids fighting constantly, Liu Yijiu felt a little sleepy and said he would take a rest.

Although these things are simple, almost five hours have passed since they were over eleven o'clock.

Liu Yijiu went outside to open the door, and the cold wind with moisture rushing from outside immediately made him feel excited and he woke up a lot.

"Do you smoke, master? Do you often stay up late in the mountains? Can you survive without smoking?" Liu Yijiu did not smoke, but rarely smoke.

Staying up late, both for him and for his body, has long been used to it.

He nodded and took the cigarette without a mouthpiece handed over by Qin Huaibao. After lit it, he took a deep breath. The spicy and stimulating smell of smoke spiraled in his lungs and then came out. Liu Yijiu immediately started coughing.

This thing is so choking.

"Why are you two still not sleeping so late?" A voice suddenly came from the darkness next to you, which scared the two of them. When they saw that it was Xie Heping.

Liu Yijiu greeted him.

"Director, why don't you rest when you're so late?" Qin Huaibao immediately smoked a cigarette and handed it to Xie Heping, and then drew a match to help him light it.

"As people get older, they sleep less. I'm already awake. Looking at the design room here, I thought you forgot to turn off the lights. Although the electricity cost is low, it still needs to be saved." Xie Heping let the smoke burn for a long time, "Aren't your projects almost the same? Are you doing some new projects?"

"No, I have a new optical equipment here that needs help from Factory 298. I can't get away with the work inside, so I can only let Huaibao go there. He doesn't know much about these things, so I can only give him a surprise attack and let him remember it. It will be much easier to communicate with him in this way. By the way, explain the principles, structures, and precautions of these drawings, so that he can better convey our requirements there..." Liu Yijiu explained to Xie Heping.

Xie Heping would patrol the base every day and in the middle of the night. Liu Yijiu knew it.

"Xiao Liu, the body is the capital of the revolution. If you are so young, you have such talent, so you have to pay attention to your health. Otherwise, it will be a huge loss to our national defense system. We have suffered a lot in the previous years. The talent training has been broken again..." Xie Heping sighed.

The young man Liu Yijiu, like the old guys inside, is very hard-working.

However, from this, it can also prove how hard this young man has worked during the years he has studied outside.

He knows a lot, and no one doubts anything else.

"Director Xie, go and rest first. We are almost finished here." Liu Yijiu still had a small piece of cigarette in his hand, but he was not used to the smell, so he threw the cigarette butt on the ground and stomped it out with his feet, then picked up the cigarette butt and threw it into the trash can behind the door.

"I'll also hear what you've written. I can't sleep when I go back..." Xie Heping suggested to Liu Yijiu that he wanted to listen.

Liu Yijiu did not refuse, and Xie Heping could not disclose their secrets.

"You must remember this drawing. Then you will draw sketches on their demonstration board. Let's not care about what they do. I just need to become famous, remember, right?" Liu Yijiu knocked off again.

Qin Huaibao nodded.

"I have marked this structure above. The assembly diagram is from left to right, and the outermost part is an objective lens that receives visible light and near-infrared images, followed by a photocathode, then a fluorescent screen, followed by an optical fiber panel... It is divided into three levels, three levels are coupled and enlarged step by step..." Liu Yijiu wanted to explain this assembly diagram and inform him of the working principle.

Qin Huaibao's mind was blank when he heard it, but Xie Heping listened with relish.

This made Liu Yijiu feel very strange.

Is Xie Heping still an expert in this field? It shouldn’t be!

"In the lens, tell them that it is best to experiment with zinc sulfide coating. In addition, as for the input surface of this microchannel plate, the output surface is close to the fluorescent screen..." Then Liu Yijiu was too lazy to talk about the imaging principle.

The comrades of 298 are very clear about these things. (To be continued...)
