Siheyuan: I eat melons while doing scientific research

Chapter 1112 It’s not the efforts of the old man (first two chapters)

Most of the comrades here are not technical people, but for them, it is important to understand the "screening mechanism".

"In other words, there is some way to make the light emitted different from ordinary light in nature and further reduce the interference?"

Gao Zhendong nodded: "Yes, that's what polarized light is, and it can achieve this effect." As for what polarized light is and how to obtain it, Gao Zhendong did not explain, and his comrades did not ask. At this point, this issue was not that important.

After saying that, Gao Zhendong pointed to the rectangular box next to him and said, "This box is also too big. An amplifier circuit with similar functions does not need to be so big. The most important amplifier component inside is still a vacuum tube. The whole thing cannot be small in size."

This is an old problem of the Russians, and there is no cure for it in the short term.

"If you want to improve, how would you do it?"

"Use semiconductors. They are smaller than this, more reliable, and consume less power. But this is not the most important problem. The most important problem is that the receiver and the entire circuit they use seem to be a broadband receiver, and the laser frequency band they receive is relatively wide."

"Isn't a wide frequency band good enough? This way we can receive more types of signals." It is estimated that the comrades here are engaged in radio-related work. For radio receiving devices, the wider the receivable frequency band, the better, so they felt a little strange about Gao Zhendong's words.

Gao Zhendong shook his head: "No, here, as long as it can match the wavelength of the laser, the narrower the frequency band, the better. This way it is not easily interfered with. Secondly, the signal with the same energy can produce a more significant output, which is good for anti-interference and detection. If the technical improvements I mentioned above are used, I estimate that the performance of this thing can be greatly improved while the aforementioned volume is reduced!"

The comrades from the relevant units looked at each other and said, "Okay, we understand, Comrade Zhendong, thank you very much for your explanation. If we have any questions later, we will send someone to learn from you."

The leader of the Defense Work Committee looked at Gao Zhendong with satisfaction. "Hello, Comrade Zhendong. You discovered the problem quickly, were very vigilant, and solved it quickly. From what he said, we will be able to eliminate the potential threat of this equipment soon and get our work back on track."

Not only that, we can even gain more based on this thing.

To the north, in the Russian home, the people of Lubyanka soon sensed that something was wrong.

"The laser eavesdropping equipment is almost completely ineffective within the range of our southern comrades?" An old Russian in Lubyanka asked in disbelief.

The other man shrugged. "Yes, my Davari. Just a few days after this device was put into use, almost all eavesdropping targets lost the possibility of eavesdropping. It seems that they discovered this device at the same time as we started using it, and at the same time, they developed a way to deal with it almost overnight."

At this point, the man still had a look of regret on his face: "Also, we also suffered losses in the local personnel over there. It seems that the southerners have activated a special mechanism. Some of the local personnel who were discovered disappeared very quickly."

"Special mechanism?"

"Yes, it seems to be called 'strict, severe, and quick.'" The Russian accent makes these words sound very funny, but if you are familiar with our language, you will know that these words are full of murderous intent.

The first Lubyanka member who raised the question turned to look at another person next to him. This person did not look like someone from Lubyanka, but rather had a strong technical background. "My dear Davari, you said that the eavesdropping method you invented was difficult to prevent and detect, but now it seems that the facts are somewhat different from what you said."

As expected, he was a technician, and it sounded like he was a researcher of laser eavesdropping devices. He spread his hands and said, "Yes, this method is indeed difficult to prevent, but it may not include comrades from the South. Don't forget that the first person to light up the laser was there. And I also reminded you not to rely too much on this technology and not to use it on a large scale."

No matter how difficult a technology is to prevent, once it is widely used, the possibility of problems will naturally be much greater.

This left the people in Lubyanka speechless. For them, this was a dilemma.

It is too difficult for them to restrain their greed for the benefits brought by this new technology. After all, it is almost invisible and they can directly hear a lot of content that was originally difficult to obtain.

However, if used in large quantities, it will almost certainly lead to greater risks.

Fortunately, this new equipment is not completely useless.

"In order to work, we have to take certain risks. Fortunately, the area where the problem occurred is our friends. Even if they have taken precautions against this technology, it is difficult to spread this precaution."

At this point, we are like the Northern Peninsula decades later. It is very difficult for outsiders to obtain our internal information. At this point, the people in Lubyanka seemed happy: "Anyway, this method is still very effective in places like Citibank, John Bull, Gallic Chicken, etc. So far, the harvest is still very good."

They are helpless even against these few countries, let alone other countries.

It's not that the Russians didn't work hard. It's like decades later, everyone is saying that the Citigroup started to show signs of decline due to strategic mistakes. But if we exclude us, there were actually no major mistakes in the Citigroup's strategy.

The only mistake actually came from the variable they could not control - us.

The old Russians in Lubyanka at this time and the Citibank guys decades later were actually brothers in distress.

However, the old Russian who invented the laser eavesdropping device frowned and said, "My dear Davari, I have to remind you that we must use all anti-laser eavesdropping measures in our workplace, especially for our comrades in the south."

"My comrade, are you being a little too pessimistic? We are the only ones in the world who don't have this kind of equipment."

The bugger shook his head. "My dear Davari, three days ago, that may have been the case, but now, I think you shouldn't be so optimistic. Again, don't forget that the Southern comrades are the ones who invented the laser. They have extraordinary abilities in this area. Don't forget that some of my academic papers in this area must be published in Southern journals in order to gain the greatest influence in this field."

The people in Lubyanka were shocked. The meaning of the other party's words was very clear. This kind of equipment was most likely seized by the other party. With the other party's ability in the field of lasers, it is believed that they can copy it quickly. Not only can they copy it, but they can also...

Thinking of this, he could not sit still any longer: "Thank you my Davari, you reminded me! I have to go to work now, I think it's not too late now."

He hurriedly said goodbye to the people here and went straight to his office.
-
In the southern waters, on Peace Island, the largest island in the South Cay Islands, people from Danggui Province are watching the weather radar screen.

The effect of this weather radar is not very good, but the huge size of the typhoon still makes its signal obvious on the weather radar screen, just like as long as you are not blind, you can see the sun hanging in the sky no matter how poor your eyesight is. The size of the typhoon allows the weather radar to detect them as long as it is not too poor.

"Sir, look, a typhoon ball is forming 100 kilometers away. According to the current season and wind direction, it will most likely blow towards us." A radar operator reported to his superior.

"Is the wind strong?" This is what his boss is most concerned about. If it is too strong, it will be troublesome, which means that they may need to receive the retreating troops from other islands, as well as some fishing boats, merchant ships and the like that are avoiding the typhoon.

"Based on past experience, this is not too big and should not cause people on other islands to evacuate. However, after a while, when the atmospheric activity is more intense, things may become more uncertain."

The radar operators of the weather radar are considered professionals, and their replacement cannot be done very frequently. For this reason, the families of these professionals even live on Heping Island, so he has rich experience living in this area.

"Well, I hope I don't have to hide this year, otherwise it will be another mess."

Evacuate people from other islands to Heping Island, and then rush back to garrison after the typhoon. This back and forth process is quite a lot and takes a lot of time.

He even remembered the trouble of the last evacuation, part of which was clearly seen by the maritime patrol aircraft on the other side.

This makes him always feel insecure.

"Sir, we have received a report from the Citigroup members stationed at the Citigroup base in the Lusong Islands, asking us to report our plan for dealing with the typhoon." A communications soldier came here and reported the latest requirements of the Citigroup members to the garrison commander of Heping Island.

"We report our typhoon response plan to them? They are not my father, so we won't report it!" The commander of Heping Island was not very interested in the Citigroup's arrogance and slightly out-of-line demands.

"The reason given by the other party is that they want to know our plan so that they can provide us with assistance when necessary." The signalman handed him the telegram and explained.

The commander hesitated for a moment. He still had to give some face. After all, although he was not his father, he might be the father of his boss's boss's boss. "Please help me draft a telegram to ask the main island for their opinion. If they agree, we will keep in touch with the Citibank guys and communicate at important points in the operation."

He would not make the decision on this matter himself. He would let the filial sons and grandchildren above him do it. If he made a rash decision, he would only bring trouble to himself.
