3D printing creates sensors like the "Eagle Eye"

According to reports, Professor Harald Giessen and his team from the University of Stuttgart, Germany, published their breakthrough in the field of technical optics in the journal Science Advances: researchers at the University of Stuttgart use Photo from Nanoscribe The nic Professio nal GT system prints microscope lenses of different focal lengths onto CMOS chips with high resolution. All images created by the lenses on the chip will be read out simultaneously by electrical signals and processed centrally into images with significantly improved resolution.

Prior to this, the desire to generate such a so-called "small concave imaging" required a large number of cameras and sensors, which must be installed around the vehicle in the automotive industry. Thanks to this new approach, researchers have been able to use sensors to produce cameras that reflect super-wide areas like the eagle eye. In addition to the automotive industry, researchers are also looking into the future of smartphones or medical applications.

What is the experience of having an "Eagle Eye"? Probably it is a quick distinction between surgeons and spies who look similar. Thanks to a new camera, the eye works the same way as the eagle eye, although it is not as good as a grain of salt. Using spy tools as a reference, scientists began researching microlenses a few years ago, and the new version improved the field of view and focus of the lens.

According to the report of Approaching Science, the latest version created by researchers uses 3D printers for injection molding, and its performance is no different from Hawkeye. The camera uses four lenses, each of which is set to a different focal length and mounted on an image-reading microchip that compiles the data from four lenses into a single image. These microlenses work by mimicking the principle known as foveal foveal vision, allowing many capturers to see a wide field of view at low resolution while focusing on a single object with high resolution.

The reason why humans can acquire such power is because of our fovea, a small concave on the back of our eyes, filled with cone-shaped cells that can perceive color, which is the only place where light directly illuminates the cone. The eagle has a lot of cones, so its central recess is deep, which is why people use the "eagle eye" to describe the omnidirectional vision.

However, this chip still has some limitations: its resolution is too low, for some special types of surgery, the chip is still too bulky. It takes a certain amount of time for each individual lens to be printed in 3D. However, once these restrictions are resolved, these miniature lenses will likely enter our blood vessels or be used as ultra-small unmanned reconnaissance aircraft to monitor criminals.
