Since the beginning of this century, China has made quite good progress in the field of military technology,
especially in the past 10 years. Recently, there is another good news: China has developed
a low-cost fiber optic gyroscope, which is a major breakthrough in China's missile technology!
Gyroscopes are one of the indispensable equipment for modern missiles, and fiber optic gyroscopes are the latest technology.
On March 2, the Indian media "Eurasia Times" stated that the research team led by Mao Yuzheng (sound),
a senior engineer at the Xi'an Flight Automatic Control Research Institute of China Aviation Industry Corporation,
introduced that this technology is only owned by China and the United States; In a report published in the
"China Inertial Technology Journal" on February 28, Mao and his co-authors from the Equipment Department
of the People's Liberation Army said that although China is still two years behind the United States,
China has made rapid progress in this "destructive" chip competition. The gap between China
and the United States is already very small!
The achievements in fiber optic gyroscopes can be called: a major breakthrough!
This technology is so meaningful! Since the advent of missiles, gyroscopes have been one of the main equipment,
responsible for automatically correcting the turning and pitching movements of missiles during flight.
Gyroscope technology has also undergone several generations of changes. The earliest was a mechanical gyroscope.
Now it has entered the era of fiber optic gyroscopes. It is a completely electronic product with very good performance!
Traditional fiber optic gyroscopes are relatively complex, and the manufacturing and assembly of core components
are quite troublesome. It is time-consuming and requires a lot of manpower. It is not suitable for mass production
and the cost is not cheap. Low-cost fiber optic gyroscopes belong to the latest technology. They are basically an electronic chip.
The manufacturing is quite simple. Old electronic chip factories can mass produce them. They are made using deep
ultraviolet/DUV lithography technology with a wavelength of 248 nanometers. Now mass production can achieve
chips made of 14 nanometers. This is a mature semiconductor manufacturing process.
In the eyes of the Indian media "Eurasia Times", China has successfully manufactured the only two fiber optic gyroscopes
in the world. More importantly, China can mass produce them with lithography machines. The 248-nanometer
DUV technology has a history of more than 20 years. It is not only very reliable, but also completely localized.
It can be produced almost using obsolete civilian technology. It has achieved the goal of "reducing costs, reducing size,
and significantly increasing production". The performance meets military needs and can be used for various types of
missiles and other guided weapons. The products produced are not bad either. The gap with the United States is only 2 years,
which means that the technological gap in the application field can be ignored.
The size of China's latest fiber optic gyroscope is smaller than a 1 yuan coin

Fiber optic gyroscopes are the core equipment of modern precision-guided weapons
The application of this technology is of great significance. The new fiber optic gyroscopes produced have become smaller.
The current size is about the size of a grain of rice. It is said that chip technology has reduced the size of the gyroscope
to 1/12 of the original product. You can see the comparison photos, which are only a few tenths of a one-yuan coin.
The progress is very great. The previous typical fiber optic gyroscope was the size of a rice bowl, which had a great impact.
The previous fiber optic gyroscope had to be installed on a missile, which took up a lot of space and weight.
Now it is much simpler to consider!
Don't think that the performance is poor because it is small. According to the R&D team, the accuracy has increased
by about 30% compared with the previous mainstream products. At the same time, due to the maturity of production technology,
the output is also very large. According to the R&D team, "with the help of photolithography technology, hundreds or
thousands of photon chips can be processed on a single wafer at a time," and the result is that the cost is reduced to a very low level.
The Indian media used the words of the Eurasian Times that high-end fiber optic gyroscopes have made China cabbage-like.
This is not that the traditional fiber optic gyroscope manufacturing model will be overturned, but the writing of a new technological history.
Modern guided weapons cannot do without gyroscopes
Don't think that this technology is simple. In the past, no one in the world except the United States figured it out.
China is the second country in the world to figure it out. This is in the field of technology. China has made another breakthrough!
It has more practical technical significance. This is very important for increasing the output of guided weapons.
The production cost of modern weapons is very high. The reason is not how difficult it is to find materials,
but the supply of various electronic equipment, including gyroscopes, of which the guidance system occupies a considerable share.
If the manufacture of gyroscopes becomes very simple and the cost is very low, then it can promote the development of guided weapons.
The biggest advantage of guided weapon technology is that it improves the accuracy of hits.
One of the main factors hindering its development is cost and output. If the main components of the guidance system can be produced cheaply,
then the application of guidance technology in various weapons and equipment can be greatly promoted,
and perhaps ordinary artillery shells can be guided.
Laser gyroscopes were one of the bottleneck projects before
In addition to the application of gyroscope technology in military weapons technology, there is actually a lot of application space in the civilian field.
There is a lot of application space in civil aviation, various types of autonomous driving, and intelligent robots.
The success of this technology is very important for our progress in the high-tech field.
Lithography machines are indeed a problem, but they will not always be a problem
This news is enough to give Americans a headache, because the US blockade in the relevant technology field has not
achieved any expected purpose. The United States also thought that the blockade against China
could prevent our technological progress, and is trying to blockade in the chip field,
such as: banning the export of deep ultraviolet lithography machines to China.
Not only the United States, but also its allies do not allow it. Unfortunately, reality has proved that we have not been affected.
The United States has completely chosen the way, and we can only turn pressure into motivation!
