摘要
The invention relates to the field of optical anti-counterfeiting, and discloses an optical anti-counterfeiting element and an optical anti-counterfeiting product. The optical anti-counterfeiting element comprises: a substrate which is at least partially pervious to light, comprising a first surface and a second surface opposite each other; an anti-counterfeiting image formed on the first surface of the substrate, wherein the anti-counterfeiting image comprises a plurality of imaging pixel groups, and the imaging pixel groups are arranged aperiodically and/or without an axis of symmetry; and a sampling-synthesis layer with optical characteristics formed on the second surface of the substrate, wherein target visual images corresponding to the imaging pixel groups can be presented through a light-pervious part of the substrate and the sampling-synthesis layer. In this way, at least the technical problems of poor anti-counterfeiting performance and easy cracking caused by the adoption of a periodic micro-graphic array in the prior art can be solved.
