Of course, this is not a problem for technical experts. They have proposed two methods through repeated research and experiments. One is to refract the picture imaged by the lens on the photosensitive element through the lens.

The other is to reflect the image formed by these lenses on the photosensitive element through mirror reflection.

Of course, there is a third method, which is also the most primitive method. Adjust the angle of each lens or lens so that the image is projected onto the photosensitive element.

Is it possible to do this, in fact it is possible. Although the images projected by multiple lenses are slightly different, they can still be processed very well after calculation.

Through these methods, they successfully integrated ten lenses together and developed their first compound eye camera.

However, this technology is not advanced, its technical content is not high, and it is easy to achieve. In fact, there are already compound eye cameras developed using this technology on the market.

Moreover, there are too few lenses and the structure is relatively complicated. Can multiple lenses be integrated to simplify the structure as much as possible.

The R\u0026D team proposed a bolder idea. It is not enough to compress the photosensitive elements into one piece. Can so many lenses be compressed into one.

Yes, this idea is bold enough and very novel. But it can't be achieved in real time, because the R\u0026D team has designed a special lens. It is not the traditional convex mirror and concave mirror, but a huge honeycomb optical lens composed of many equilateral octagonal convex mirrors.

In this way, this special honeycomb structure lens composed of multi-faceted honeycomb lenses can achieve the goal of concentrating many lenses in one lens.

Such a design or such an idea is indeed very genius, it can be said to be amazing, but it encountered problems in the implementation.

First of all, this kind of honeycomb octagonal lens is difficult to process and manufacture, and secondly, the focal points formed by this kind of honeycomb octagonal lens are relatively scattered, which is also a problem if so many focal points are focused. Of course, it can be achieved through lenses and reflective lenses, but there is a bottleneck in the lens manufacturing process.

Especially in the processing of tiny lenses, it is more difficult. Even after the unremitting efforts of the research team, a fly-eye lens with a diameter of 20 centimeters and 36 lenses was produced.

Through this lens verified,

This technology is feasible, and it has achieved very good results.

So the scientific research team began to contact the company's patent application registration operation management team, and began to apply for the registration of related technical patents.

On the other hand, further research is carried out, the purpose is to overcome the difficulty of lens manufacturing and further miniaturization.

After a long period of unremitting efforts, good news finally came from the Optical Imaging Technology Research and Development Laboratory, so Wu Hao, who got the news, also rushed here immediately.

Seeing that Wu Hao had just arrived, he was anxious to ask. Sun Pengfei and Yao Zihua could also feel the eagerness in Wu Hao's heart. This eagerness must be expressed by his great attention.

So Yao Zihua nodded with a smile and said: "Yes, we have made a breakthrough in lens processing technology. Just yesterday, we successfully processed one hundred and ten octagonal lenses on a lens with a diameter of 15 mm .”

"Well, fifteen millimeters, one hundred and ten octagonal lenses, how did it come true?" Wu Hao's mind is now full of question marks.

"Laser, we use laser printing technology."

Sun Pengfei smiled and led Wu Hao to the side of the test bench, then pointed to the lens under the electron microscope, and said to Wu Hao: "This is the 15*110 honeycomb optical lens we processed and manufactured. The picture presented by the microscope."

Wu Hao glanced at the finger-sized lens under the electron microscope, and then turned his gaze to the high-definition display screen.

A circular lens appeared on the screen. There was nothing special about the surface of the lens, it looked like a normal transparent lens.

It's just that inside the lens, there are many octagonal outlines, and these octagonal outlines fill the entire lens, forming a complete circular honeycomb pattern together.

Sun Pengfei smiled and introduced to Wu Hao: "We used 3D laser printing technology to print out several octahedral lenses in this transparent lens.

Using this technology, we can print octagonal lenses as small as 0.2mm. We can even print smaller lenses if needed. "

"Just carve the outline in the lens without changing its shape?" Wu Hao questioned. After all, in his opinion, it is not realistic to only carve out the outline of the lens inside.

And Yao Zihua shook his head now and said: "Of course not, if you just carve out the outline in the lens, it won't achieve the refraction effect.

Therefore, after printing the outline of the lens, we need to perform special processing on the remaining part to make it lose the characteristics of glass, so that the light can not be affected by this part of the glass. "

"How to solve the problem that the focal length of such a small lens is too short." Wu Hao asked another question.

Sun Pengfei responded first: "We still use the lens principle, which can help us lengthen the focal length of these small lenses. We can carve two or even three layers of octagonal honeycomb lenses on one lens."

Seeing the complacent expressions of the two, Wu Hao nodded with a smile and said: "Good job, I am impressed by your amazing imagination and creativity.

How is the imaging effect? ​​Have you tested it? "

Hearing Wu Hao's words, both of them shook their heads and said: "At present, we have only processed the lenses, which is the first step in the whole research and development process of the compound lens, and there is still a long way to go.

How to realize the corners of these octagonal honeycomb lenses, how to assemble them, and how to develop photosensitive elements suitable for octagonal honeycomb lenses. How to extract these image information, these are the topics we will study in the future. "

Wu Hao nodded when he heard the words, then patted the two of them on the shoulders and said: "It doesn't matter, anyway, you have successfully developed the most difficult shaped honeycomb lens, I believe that the next problems will not be difficult for you, and I feel sorry for you." Have confidence."

"Thank you, Mr. Wu!" The two immediately thanked him.

Wu Hao shook his head when he heard the words, and then said kindly to the two of them: "Come on, tell me again, how did you come up with this method, and how did you realize it..."
