Modify the title: Hexagonal honeycomb compound eye lens
Of course, this is not a problem for technical experts, who have come up with two methods through repeated research and experiments. One is to use a lens to refract the image imaged by the lens onto the photosensitive element.
The other way is to reflect the image imaged by these lenses onto 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 to project the image onto the photosensitive element.
Is this feasible? In fact, it is possible. Although the images projected by multiple lenses are slightly different, they can still be processed very easily after calculation.
Through these methods, they successfully integrated ten lenses and developed their first compound-eye camera.
However, this technology is not advanced, the 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 complex. Can multiple lenses be integrated to simplify the structure as much as possible?
The R&D team came up with a more bold idea. It is not enough to compress the photosensitive element into one piece. Can so many lenses be compressed into one.
Yes, this idea is bold enough and very novel. But it cannot be realized in real time because the R&D team designed a special lens. It is not the traditional convex mirror and concave mirror, but consists of numerous
A huge honeycomb optical lens composed of equilateral hexagonal convex mirrors.
In this way, wouldn't this special honeycomb structure lens composed of multi-faceted honeycomb lenses be able to achieve the goal of integrating many lenses into one lens?
This kind of design or this kind of idea is indeed very genius and can be said to be amazing, but it encountered problems in its implementation.
First, this honeycomb hexagonal lens is difficult to process and manufacture. Secondly, the focus formed by this honeycomb hexagonal lens is relatively scattered. This is also a problem if so many focus points are focused. Of course, through the lens and reflection
The lens can be realized, but there is a bottleneck in the lens manufacturing process.
Especially in the processing of tiny lenses, it is even more difficult. Even after unremitting efforts, the research team was able to come up with a compound eye lens with a diameter of 20 centimeters and 36 lenses.
Through this lens, it has been verified that this technology is feasible and 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 registration of relevant technology patents.
On the other hand, further research is carried out with the purpose of overcoming the difficulty of lens manufacturing and further miniaturization.
After a long period of unremitting efforts, good news finally came from the Optical Imaging Technology R&D Laboratory, so Wu Hao, who got the news, also rushed here as soon as possible.
Seeing that Wu Hao was eager to inquire as soon as he arrived, Sun Pengfei and Yao Zihua could also feel the eagerness in Wu Hao's heart. This eagerness must be manifested by great concern.
So Yao Zihua smiled and nodded: "Yes, we have made a breakthrough in lens processing technology. Just yesterday, we successfully processed one hundred and ten hexagonal lenses on a lens with a diameter of 15 mm.
.”
"Well, fifteen millimeters, one hundred and ten hexagonal lenses, how to achieve it?" Wu Hao's mind was now full of question marks.
"Laser, we use laser printing technology."
Sun Pengfei smiled and led Wu Hao to the edge of the test bench, then pointed at the lens placed under the electron microscope and said to Wu Hao: "This is the 15*110 honeycomb optical lens we have processed and manufactured.
The picture presented by the microscope."
Wu Hao glanced at the lens about the size of a finger under the electron microscope, and then turned his attention to the high-definition display screen.
I saw a circular lens appearing on the screen. There was nothing special about the surface of the lens. It looked like an ordinary transparent lens.
It's just that inside the lens, there are many hexagonal outlines. These hexagonal outlines fill the entire lens and together form a complete circular honeycomb pattern.
Sun Pengfei smiled at Wu Hao and introduced: "We used 3D laser printing technology to print several hexagonal lenses inside this transparent lens.
Using this technology, we can print hexagonal lenses as small as 0.2 mm. We can even print smaller lenses if needed."
"Just carving the outline into the lens without changing its shape?" Wu Hao questioned. After all, in his opinion, it is a bit unrealistic to just carve out the outline of the lens internally.
Yao Zihua now shook his head and said: "Of course not, if you just carve an outline into the lens, you won't be able to achieve the refraction effect.
Therefore, after printing the lens outline, we need to perform special processing on the remaining part so that it loses the characteristics of glass so that the light is not 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 raised a question again.
Sun Pengfei was the first to respond: "Using the lens principle can help us extend the focal length of these small lenses. We can carve two or even three layers of hexagonal honeycomb lenses on one lens."
Looking at the proud expressions of the two people, Wu Hao smiled and nodded: "Well done, 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 lens. This is the first step in the entire compound eye lens development process. There is still a lot of road to go.
How to make these hexagonal honeycomb lenses realize corners, how to assemble them, how to develop photosensitive elements suitable for hexagonal honeycomb lenses. How to extract this image information, these are all topics we will study in the future."
Wu Hao nodded when he heard this, then patted the two of them on the shoulders and said: "It doesn't matter, anyway, you have successfully developed the most difficult honeycomb lens. I believe that the following problems will not be difficult for you. I am very concerned about you."
Have confidence."
"Thank you, Mr. Wu!" The two of them thanked him immediately.
Wu Hao shook his head when he heard this, and then said kindly to the two of them: "Come on, tell me again, how did you think of this method, and how did you implement it..."
