METHOD OF APPLYING WAVY TEXTURE ON SURFACE

摘要

FIELD: process engineering. ^ SUBSTANCE: invention may be used for producing textured substrate to write data thereon in the form of code. Proposed method comprises focusing laser spot on the surface and transfer of preset-diametre and depth surface brought about by local evaporation of material along recesses of wavy texture being applied. In mixing local evaporation zone, a small-scale oscillation of zone position is initiated. Note here that oscillation amplitude does not exceed half the diametre of local evaporation cone. ^ EFFECT: small-scale intermittent wavy texture that allows reflection without glare at all angles of optical radiation incidence on etched surface. ^ 5 cl, 2 dwg
