This powerful "spy camera" can capture facial details from over 60 miles away

Serving tech enthusiasts for over 25 years.TechSpot means tech analysis and advice you can trust Forward-looking: Researchers in China have developed an exceptionally powerful synthetic aperture lidar system that could enable the nation to scrutinize foreign assets – particularly military spy satellites – with unprecedented precision. They have already demonstrated its ability to capture highly detailed images from more than 60 miles away. Worse still, if this technology were deployed in low Earth orbit, it could potentially distinguish details as fine as a human face, according to the South China Morning Post, which cites a peer-reviewed study published in the Chinese Journal of Lasers. The researchers from the Chinese Academy of Sciences achieved this breakthrough by integrating multiple pioneering technologies into a cutting-edge laser system. By splitting the laser beam across a micro-lens array, they increased the aperture size while maintaining a wide field of view. Specialize ... Read full article.
