美国加利福尼亚大学的科学家发明了一种激光消尘器。该消尘器内装有微处理机控制的高速扫描装置能够自动寻找周围的粉尘,一旦发现粉尘,即发出红外激光,在一瞬间可将粉尘烧尽。这种激光消尘器去尘面积可达200m2,在消除粉尘时,并不会损坏物体。激光消尘器@李玲玲 Scientists at the University of California, Los Angeles, invented a laser cleaner. The microprocessor-controlled high-speed scanning device in the dust collector can automatically look for the surrounding dust. Once the dust is detected, it emits an infrared laser and can burn out the dust in an instant. This laser dust collector to dust area up to 200m2, in the elimination of dust, and will not damage the object. Laser dust collector @ Li Lingling
