FIELD: physics. ^ SUBSTANCE: retro-reflective coating contains a number of angled reflective elements of preferred geometry with surfaces determined by a set of transverse grooves. At least, two grooves of the set are not parallel by the value within nominally parallel position, i.e. position whereat groove direction are not induced with intentional deflection within precision rates of groove-making machine to the position at the angle about 1°. ^ EFFECT: ease of application with improved performance reliability. ^ 14 tbl, 33 dwg, 3 cl |
