Scientists Invent Laser Technology to Read Small Distant Text

A team of scientists from the University of Science and Technology of China has developed a laser technology capable of reading small text from nearly 1.5 kilometers away. According to their claim, this new laser technology can read any character with a 3-millimeter resolution from a distance of 1.36 kilometers. The findings were published in the journal Physical Review Letters.

According to the scientists, the new laser technology was developed based not on focusing on distant images, but on how light interacts with a surface. The system emits eight infrared laser beams at a specific point. The intensity of the reflected light is then captured using two telescopes. By analyzing the captured data, it becomes possible to observe tiny text and fine details at high resolution.

In practical tests of the new technology, scientists successfully captured images of small-sized targets located 1.36 kilometers away. They stated that the resolution of the image is about 14 times higher than the evolutionary limit of any single telescope.

Scientists believe that this new method can be used for high-resolution optical imaging and sensing. In the future, combining this technology with artificial intelligence could enable even more effective information analysis.
