FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. The article surface structure has machined part resulted from photo decay related to the fed of pulse laser light. Note here that periodic microstructure that allows the structure light to originate. Said microstructure has multiple machined parts arranged regularly as the reticule cross points and is formed at the article one area. Each of said multiple areas produced by separation of the surface. Each of said areas is that of the formation of the areas. One or several areas are located in one of the latter. Besides, it defines the directions of machine parts configuration, said parts being formed in every area, the directions change in compliance with the zones of areas formation.
EFFECT: claimed structure allows a visual recognition of structured light at whatever angle of vision to facilitate the decorative effect relates to structure light generation.
