【 摘 要 】
Annotation. A simple and affordable method for estimating the contrast of laser marking with QR-code using a profilometer is proposed. The method is based on the existence of a direct relationship between the contrast and the roughness of the code - the contrast increases with an increase in the surface roughness. The use of a profilometer makes it possible to determine the features of a complex relief that negatively affect the contrast of the code.
