Breakthrough Tech Turns Any Wall into a Corner-Seeing Camera

Speedy Summary

• Researchers have developed algorithms capable of converting any rough surface, such as a wall, into a device to reconstruct hidden images.
• the technology works by unscrambling light waves that bounce off surfaces, allowing users to view objects obscured from direct sight.
• Wenwen Li from the University of Science and Technology of China explained that this process involves turning blurry reflections into clear visuals, likening it to transforming a rough wall into a mirror.
• Potential applications suggested include military use for enhanced surveillance.
