Patent abstract
A method and a device for processing a unidirectional flow surface, the method includes: generating a grayscale map having gradually changed grayscale values; generating a holographic phase map having a bionic light spot with gradually changed energies based on the grayscale map; loading the holographic phase map onto a spatial beam shaper; and focusing a laser beam on a surface of an object to be processed after the laser beam passes through the spatial beam shaper, to process structural units having unidirectional flow characteristics on the surface of the object to be processed.
