An optical anti-counterfeiting element comprises a base material (11). The base material (11) has a first surface and a second surface which are opposite to each other. The first surface is covered thereon with a micro-sampling tool (12); one part of the second surface is a micro image-text formed by a micro relief structure (13), and the other part thereof is a flat structure which does not form a micro image-text and/or a micro relief structure (14) which is different from the micro relief structure forming the micro image-text. The flat structure which does not form the micro image-text and the micro relief structure (14) different from the micro relief structure forming the micro image-text are homomorphically covered thereon with a first plating (15), the micro relief structure (13) forming the micro image-text is homomorphically covered thereon with a second plating (16), and the micro image-text is sampled by the micro sampling tool (12). Also provided is an anti-counterfeiting product using the optical anti-counterfeiting element and a preparation method therefor.

The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acquisition and computing device such as a smartphone. The superposition shape images may be created by different superposition techniques ranging from 1D moir, 2D moir and level-line moir superposition techniques to lenticular image and phase shift superposition techniques. Moir superposition techniques enable creating superposition shape images at different apparent depth levels. Applications comprise the protection of documents and valuable articles against counterfeits, the creation of eye-catching advertisements as well as the decoration of buildings and exhibitions.
