After many studies, the experts of the universities Princeton y Washington They found a way Photo tool The same amount of salted grain with capacity Processing images High quality. I.e. a great invention and progress Medical and Scientific AreaIt will open the door to the most detailed study of the human body.
Although some already Nano cameras Are used in the medical field to perform functions and analyzes such as those involved Endoscopies Or if the brain took pictures, the features they captured were bad.
Unlike Professional cameras or cell phone cameras The more powerful, the smaller ones have inherent technical limitations to their size.
“We have designed a completely different learning framework Learn a physics meta-surface structure With a mechanism for image reconstruction based on neurological characteristics, ”they explain in the article.
By “metaserface”, they each represent their new structure with an optimal surface area of 1.6 million cylindrical posts in half a millimeter. These poles act as light receiving antennas Image instructions.
Therefore, the invention of members of American universities has caused a stir because of the smallest camera and the best Image processing They can perform new clinical trials or be used where needed.
They point out that the camera has been shown to work up to the 2.0 aperture, which means it can capture images even in low light conditions.
They also pointed out that by reducing the focal length of the camera, they were able to reduce the color changes that represent the color of the image. With all of these, they can recreate clearer photos than photos already in the field.
“We are jointly developing the meta-surface and deconvolution algorithm With an imaging model that can vary from end to end, ”they explain.
They pointed out that they were able to overcome by their investigations the current patterns of some construction defects that are outside the normal wavelength range in test captures, which demonstrates the quality of the image.
“In our model, the polynomial coefficients that determine the metasurface phase are optimal variables, while the test-measured parameters that characterize the sensor reading and sensor-metasurface distance are constant”
To put it more simply, the Photo tool While the parameters of other models are measured and fixed according to experience, it has the potential to be modified to its predecessor variables (such as an automatic mode).
Other than that, they mentioned their construction The device simulates neural networks It facilitates learning at low and high levels, while at the same time allowing information to be encrypted and propagated beyond processing and transmitting.
The Princeton and Washington researchers Despite inventing a low-resolution camera with no chromatic variations, they prefer to extend their work to flexible images. Nanophotonica Can be reconfigured for various tasks such as sorting or locating objects.
Finally, the developers of this technology have mentioned some future benefits and applications related to their invention. “We hope the proposed system will take a major step Very small cameras This will allow new applications to be distributed on endoscopy, brain imaging or object distribution. ”
