The heart has repaired the new scientific research center, and the scientific research department of the Institute of Optics and Mechanics can say goodbye to the dilapidated bungalow, after all kinds of equipment are installed in place, the adaptive optics department is indeed very magnificent, and when Wang Zhengguo saw the chief engineer Jiang, it happened that he walked out of the laboratory to breathe.

In terms of appearance and temperament alone, it does give people a sense of academic leadership in scientific research, and it is worthy of being able to develop an internationally leading level of adaptive optics in just a few years from nothing, and later can be elected as an academician of the Academy of Sciences, and they do have capital.

"Chief Engineer Jiang, hello!"

It's rare to come out and take a breath, and after you're in a good mood, you can speak casually: "Oh, hello." What's the matter?"

"Well, yes, I just visited the product exhibition hall of the institute and saw a set of ballistic cameras, and I want to know if the institute is still engaged in this kind of research?"

When it comes to ballistic cameras, this makes Chief Engineer Jiang very touched, this is the first time he has been responsible for the development of the whole machine equipment since he started his work.

Although he has also participated in the development of many precision instruments, including the development of large-scale cinema theodolite for aircraft, rocket and spacecraft trajectory measurement, landing and flight live recording, he undertook the design of the large-scale azimuth turntable of the equipment, which is also a very key subsystem.

The development of large-scale film theodolite enabled him to verify the idea of friction transmission of large-scale theodolite proposed by Wang Daheng in practical work, which opened up a new way for the precision transmission of large-scale precision tracking equipment.

He himself put forward the theory of the accuracy of large-scale planar shafting, and proposed a self-benchmarking three-point method to measure the flatness of large rings, which successfully solved the problem that micron-level thrust bearings could not be measured at that time, and the method was still reliable after 2000 in the development of similar equipment.

The development of the film theodolite did make him emerge temporarily, but due to family composition, he was still refrigerated in that special era, and even transferred from the top Ivy Optical Machine Institute in the domestic precision optical industry at that time to the newly established three-line Shudu Optical Machine Institute.

Many people in the third-line construction were actually rejected by the original unit for various reasons, so they came to the third-line and started their own different lives.

Chief Engineer Jiang, who came to the third line, still failed to obtain the right to directly lead a project, and after a few years, he got the task of developing a ballistic camera, and then he had the matter of translating on the folding board of the sewing machine, which was stressful, enthusiastic, and responsible.

Fortunately, the ballistic camera was finally developed, and then he participated in the development of lithography machines, and these many times he switched to the development of different types of precision equipment, and all of them were successful, which provided a solid foundation for his research on adaptive optics, a new technology that integrates optics, mechanics, electronics, computing technology, materials and other disciplines.

Although the things he is researching now are very challenging and the results are not bad, Chief Engineer Jiang is still very affectionate about the ballistic camera he was responsible for developing for the first time, and he has always paid attention to ballistic cameras.

"Of course, this thing is the first national project successfully developed after the establishment of our Shudu Institute of Optics and Machinery, and although it has been delivered for many years, it still plays a key role in the field of first-line optical measurement and control. ”

Obviously, it was wrong for someone to guess that the ballistic camera of the Institute of Optics and Mechanics had been retired from active service, and it was clear that they were still in service, and they were getting stronger!

"That's great, but I would like to ask, does the institute still need to pre-develop the next generation of ballistic cameras? If so, I might be able to provide some advice and cooperation to make a new product that is disruptive and guarantees a huge leap in performance. ”

Time is precious for everyone, and it can't be wasted on meaningless chatter, Wang Zhengguo directly explained his intention, he is planning to jointly develop the next generation of ballistic cameras with the Institute of Optics and Mechanics, and now we need to see what Chief Engineer Jiang thinks.

To say that the gap between this digital camera and the traditional film camera is indeed very large, the breakthrough in performance, it is definitely not an exaggeration to use the word "leap" to describe it, in the field of ballistic cameras, the transition from film to the digital age, is a world of difference.

In fact, the specific engineering projects of the Institute of Optics and Mechanics were only started after the state approved the project, and the state did not formally propose to update the ballistic camera, which did not conform to the law of the development of such equipment as ballistic cameras.

But then again, it is feasible to carry out pre-research preparations in advance, and only after the basic skills are done, can we quickly come up with qualified products when we want to start developing them next time, so as not to be robbed of the meat in our bowls by other brother units.

There are many units engaged in the research and development of precision optical equipment in the Republic, namely the Ivy Optical and Mechanical Institute in the northeast, the Chang'an Optical and Mechanical Institute in the northwest, the Shudu Optical and Mechanical Institute in the southwest, and the Modu Optical and Mechanical Institute in the southeast.

Out of a strong sense of crisis, Chief Engineer Jiang was very interested in the "performance leap" proposed by Wang Zhengguo: "Let's talk about how to achieve your so-called huge leap, if you guess correctly, you don't even know the performance parameters of our DX-190 ballistic camera of the Institute of Optics and Mechanics, why are you so confident?"

It's true that I don't know the parameters, but this doesn't mean that someone doesn't dare to boast about Haikou, no matter how good the traditional film camera is, it can't be compared with the digital camera, this is an iron law.

"It's true that I don't know how well it performs, but I know that it's a film camera, and what I'm proposing now is to complete the development of a digital ballistic camera based on a CMOS optical sensor, which brings advantages that can make up for many of the shortcomings of existing film ballistic cameras. ”

The shortcomings of the 190 ballistic camera are obvious, first of all, the inherent flaws of film cameras: to come up with the results, there must be a process of processing, interpretation, etc.

The digital camera mode is completely different, this thing can be directly displayed on the computer in the form of digital signals, and the relevant data can be analyzed on the computer through special software, and more detailed and comprehensive results can be obtained, which is absolutely impossible for traditional ballistic cameras.

The output and analysis of data results is a great change for ballistic cameras, and in terms of the requirements of ballistic cameras for the use environment, digital ballistic cameras with CMOS sensors can also have better environmental adaptability.

Unlike film ballistic cameras, which use repeated exposures to obtain ballistic trajectories, digital cameras use frame-by-frame measurements, which will enable ballistic cameras to work around the clock.

In the past, film ballistic cameras could only work on dark backgrounds because of the repeated exposure design, and the background light energy needed to accumulate continuously during measurement, and generally speaking, the ballistic trajectory test could only be carried out in the dark at night, which caused great inconvenience.

The frame-by-frame measurement of the digital ballistic camera can be fully adapted to the strong light background during the day, which is convenient for testing, and also provides the possibility for those who can only perform ballistic tests during the day.

The first two advantages can already satisfy the leap progress that Wang Zhengguo said, but compared with the last advantage, they are not too important.

The in-depth development of the software supporting the digital ballistic camera will completely solve the problem that the traditional ballistic camera can only test the trajectory of a single target, which enables the ballistic test work to enter the multi-target era in one fell swoop.

In the testing of multiple rocket launchers and close defense systems, the problem of mutual influence on the trajectory of different shells (bullets) after firing can finally be supported by specific image data and "targeted improvement", which will no longer be an empty word.
