Chinese researchers say they have developed the world’s most advanced laser for wind detection, which could be used to monitor air pollution, predict the weather, and make high-speed trains faster.
The suitcase-sized device can detect complex changes in wind in unprecedented detail by using lidar methods. Lidar, or light detection and ranging, works by detecting the relative movement of air in the atmosphere with a laser.
