Bright Sword Military System

The invention of the laser is not difficult to say, but it is not easy to say simple.

To put it simply, before Mayman used ruby ​​to create lasers, all scientists and authoritative organizations in the world said that ruby ​​​​was not good, and even gave a lot of calculations to prove that ruby ​​​​was not good.

But Mei Manli just didn't believe in this evil, so he wanted to use rubies to make it, but he slapped everyone in the face.

It’s hard to say, the entire experimental device is the size of a suitcase, and the space has not been optimized... Wang Xuexin bought this device and the detailed manual with [-] million military industrial coins. Forget it, the important thing is technology, not space, and it is not difficult to miniaturize such a simple device by itself.

All it takes is: a high voltage power supply, energy storage, a helical xenon flash (something like a spring), plus ruby ​​rods and resonant chambers, and a semi-reflective mirror and a fully reflective mirror and that's it.

If there is any difficulty in this, it is the ruby ​​rod. It requires a ruby ​​with a chromium content of 0.05%, and it is processed into a shape of 1.9 cm in diameter and 0.95 cm in diameter. Plated with silver.

This ruby ​​stick Wang Xuexin imported directly from Yingjiang.

This is what Wang Xuexin said to Sun Erwei: "Major, I need such a kind of ruby... She is very picky about this thing, she wants to be like this..."

Sun Erwei's interest is not in ruby ​​at all, he immediately let out a burst of laughter: "Wow, 'her'? I didn't expect our leader to be very good at pleasing women! When will you introduce her to me?"

Wang Xuexin replied: "Do you think I'm stupid, Major? If I introduce you, will I be worried that you will snatch her away?"

Sun Erwei on the other end of the phone laughed "haha": "Don't worry, Wang! I'm not going to be a woman who steals friends!"

Wang Xuexin deliberately misunderstood Sun Erwei, so as to save a lot of trouble, such as Yingjiang asking questions or secretly tracking down what the Eighth Route Army wanted this kind of ruby ​​for.

Ying Jiang was quite generous in this respect, and soon sent a pair of rubies that Wang Xuexin requested, and even packed them in an exquisite gift box and sent blessings with a small greeting card... Sun Erwei must have thought that Wang Xuexin wanted to use these rubies to give to Wang Xuexin. Someone proposes.

Su Liguo can handle other things.

Throughout the whole process, Su Liguo had the mentality of giving it a try, and part of the reason was that the person who asked for the experiment was Wang Xuexin... If it was someone else, Su Liguo would have quit and said it would be impossible.

But having said that, Su Liguo still carried out every step seriously.

The moment Su Liguo connected to the power supply, the xenon flash flashed in the closed box with a "snap", almost at the same time a red light shot out from the launcher and hit the total reflection mirror and then hit the experimental bench.

Wang Xuexin didn't react at all. He thought it was normal, because everything was made according to the data given by the system, including the voltage, so it was only natural that he could get this result.

But Su Liguo was stunned by what he saw. He was stunned for a while before he asked Wang Xuexin suspiciously: "Tuan...Tuan Leader, did you see it? Is it my eyesight?"

Wang Xuexin raised his head towards the experimental platform: "Are you dazzled, don't you know by looking at the received data?"

A word awakened the dreamer, Su Liguo hurriedly inspected the receiving equipment on the experimental platform, and then cheered in surprise and joy: "Head, there is... there is data, although it is very small, the wavelength is only 694 nanometers!"

Then Su Liguo fiddled with the accumulator again like crazy, he was worried that the result of the experiment just now was just a coincidence.

But Wang Xuexin knew that this was not an accidental phenomenon, and the laser was indeed born in his hands.

The first application after the advent of the laser was distance measurement and it was successfully used in the military field... within half a year. (Note: The laser was discovered in 1960, and the military laser range finder passed the acceptance test in the US military in early 1961)

The reason why it develops so fast is that with the laser, the main difficulty in inventing the range finder is not the laser but the computer... The computer controls the laser pulse and stores the time information into the pulse like the ultrasonic pulse of the mercury delay memory (with Light represents '1', no light represents '0').

However, the change speed of this pulse is too fast for the human eye to distinguish, so it can't feel the breakpoint at all when it fires.

In addition, the calculation problem also needs to be solved by the computer. The time interval between laser emission and reflection is too short for people to feel it at all, and of course it cannot be measured manually.

The final data obtained is also very small, and finally multiplied by the speed of light and divided by 2 to obtain the distance of the target.

It is conceivable that without the support of computers, it is difficult for lasers to develop in the direction of distance measurement.

Then Wang Xuexin handed over the matter of the laser to Su Liguo. If he wants to develop a range finder, he just needs to combine it with a computer... This aspect can even be modified directly from the positioning system without starting from scratch.

However, Wang Xuexin thinks that there is still one thing that needs to be prepared in advance: this kind of range finder will be used on tanks in the future. If each tank needs a range finder, it means that a lot of rubies will be needed.

It is definitely not acceptable to import all of them from Yingjiang, as doing so will make Yingjiang suspicious.

Do rubies have to be self-produced and processed?

Not impossible, there are not too many technical problems.

But the Eighth Route Army is already busy enough, all kinds of equipment have to be produced, and now even this little technical thing has to be done by itself... Isn't it a bit uneconomical!
After thinking about it, Wang Xuexin knew what to do.

This matter can be directly handed over to Huaxia's luxury merchants!

The base areas of the Eighth Route Army definitely don’t have such “talents” anymore, but the stubborn army has always had this need, even if they moved to Chongqing when the common people were still hungry.

It is said that there are people in Chongqing who squandered millions of dollars in just a few days of visiting the United States, and even Ying Jiang can't stand it.

In this case, the luxury merchant should be able to supply the rubies needed by the Eighth Route Army, and at worst, take it back and plate it with silver, so that there will be less suspicion.

However, even if Yingjiang and others doubt it, it is useless. Anyway, this thing will start to be sold again soon... Once the Eighth Route Army computer is upgraded, the range finder will also be updated, and the outdated things can be released immediately to reap a lot of benefits.

What should I buy then?
Having money and nowhere to spend it is also a headache...
