In this era, there is no particularly advanced energy source. So this kind of equipment not only lasts for a short time, but also has a short distance to see. For a shooter, a distance of one or two hundred meters is enough. But if it is for the pilots in the sky, this kind of thing is purely tasteless.
Qin Baoshan continued: "In addition to this kind of thing, there are actually other principles of infrared night vision devices. For example, as long as it is not the darkest night, there must be light. We can't see it, but a certain Some animals can see. It's just because too few photons hit our retina to form perception. If we amplify this faint light, people can see it."
Qin Baoshan tried his best to explain in a simple way, and Major Cromlin could understand it. Sure enough, Major Cromlin nodded now: "It is indeed a way of thinking to amplify the faint light, but how to amplify it?"
I saw Qin Baoshan smiling and began to draw a picture on a piece of paper.
The night vision device of the infrared headlight belongs to the first generation, and the second generation is the low-light night vision device. As the name suggests, it brightens the weak light. The maturity of this technology has reached the 1960s. With the invention of multi-alkali photocathode, optical fiber panel and the improvement of the design theory of concentric sphere electron optical system, the first generation of micro-light tube (the core component of night vision device) finally Appear. It can amplify the weak light, and a single tube can achieve about 50 times the brightness gain. Of course, it is not enough to magnify only 50 times. Therefore, the commonly used night vision device is cascaded through three stages, which increases the brightness by 50 times. In this way, the scene of the starry night is magnified to the brightness condition required by the naked eye to observe the object normally.
Compared with the first generation, this night vision device is a passive observation method, without infrared headlights, and will not expose itself. Moreover, it is small in size and weight, and can be mass-produced; as for the disadvantage, it must have light, even if it is a few stars, if it is a dark night where you can't see your fingers, you really can't see anything.
This picture of Qin Baoshan surprised Major Kromlin. He did not expect that Qin Baoshan really had such a talent. It was obviously just a sketch drawn by hand, but it was so precise. It can be sent directly to the factory as a production drawing, and they are indeed capable.
Think again about the many things Qin Baoshan has made: intermediate-powered rifle bullets, automatic rifles, napalm bombs, etc. Basically, there is nothing he can't do. Such a person must be invited to the United States, even if he does not live in the United States, but only stays in the United States for a period of time, it can still play his role.
The major of Cromlin listened to Qin Baoshan's introduction with surprise and exclamation in his heart. To be honest, he didn't understand. Because Qin Baoshan said a lot of professional terms. It is because you don't understand that you will appear taller. After listening to it, Major Cromlin asked Qin Baoshan cautiously: "Can I take this drawing with me?"
It can be said that this blueprint is the core of the night vision device. Can Qin Baoshan allow himself to take it away? If he didn't take it away, how would he explain these things to the experts who studied night vision devices when he went back?
Just when Major Kromlin was thinking about how to persuade Qin Baoshan if he refused to agree, Qin Baoshan nodded generously: "Of course there is no problem, you can take it away."
Anyway, it's just a picture. To turn this picture into reality, it requires a high industrial processing capacity. Qin Baoshan can't do it here, and I don't know if the Americans can do it. But Qin Baoshan knew that this picture was in the hands of those experts. It will definitely surprise the other party, this is the latest generation of night vision goggles theory. As long as you can let the other party know that you are a genius, then the other party will come to ask for advice, and you can build these relationships.
Hearing that Qin Baoshan agreed, Major Kromlin was very happy. He quickly folded up the picture and put it in his pocket, for fear that Qin Baoshan would suddenly regret it.
"My friend, thank you for allowing me to take this blueprint away. I promise, this blueprint will definitely bring out the greatest effect."
Qin Baoshan nodded: "I am also very happy. It is a pity that our technology level here is not high enough to produce these things. I hope that the United States can produce these things and provide us with a batch. Of course, if we cannot provide For these most advanced models, it is also possible to provide us with some backward models. It would be even better if you can provide us with more machinery and equipment.¡±
Anyway, I want to say something, say what I want, first say my request, and then talk about whether the other party can agree. After Qin Baoshan said this, Major Cromlin nodded quickly: "When I go back, I will definitely hand it over to the relevant experts. They will definitely be interested. In this regard, we may be able to study together and make progress together. I will convey your needs. "
It is still unknown whether this kind of thing can be fooled out of the hands of the Americans. For Qin Baoshan, being able to obtain these things is the icing on the cake. If he can't obtain these things, he has nothing to lose. It's just a whim.
Before I knew it, the sky was slowly getting dark. After the American crew members had dinner, they boarded their planes one after another. Licheng Airport became lively again, and bombers came out of the hangar and flew into the sky.
Watching the American bomber unit leave, Qin Baoshan let out a long breath, and then said: "Today's work is over, I should go home."
"Brother Baoshan, why are you so attached to your family recently?" Li Yunlong asked Qin Baoshan curiously. This has never happened before. Even if Qin Baoshan's work is not very busy recently, but he always runs home when he has nothing to do, that's really not manly enough.
Qin Baoshan smiled: "Old Li, you are a full man who doesn't know that a hungry man is hungry. You can sleep with your wife in your arms every night when you go home. How can you feel the pain of others?"
Hearing Qin Baoshan's words, Li Yunlong heyed a few times there, and then said: "It's his grandma, you have the nerve to say it. Ever since your son got on the kang, I haven't made love to my wife. Your son wants to After waking up several times, I even poured urine on him several times.¡±
Regarding this matter, Li Yunlong obviously has some resentment. Hearing what he said, Qin Baoshan immediately said: "Then I will go to your house now and take my child back. I don't know what happened to Wei Shuqin, how can I send the child away without my permission?" Agree." (Remember the site URL: www.hlnovel.com
