Abstract: 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.

Abstract: The present invention discloses an optical anti-counterfeiting component and an optical anti-counterfeiting product. The optical anti-counterfeiting component comprises: a substrate; a sub-wavelength surface micro-structure and an optical reflection facet formed on an upper surface of the substrate; and a multi-layer structured coating formed on the sub-wavelength surface micro-structure and the optical reflection facet. In the case where the same multi-layer structured coating is used, a contrasting optical characteristic is formed between the region in which the sub-wavelength surface micro-structure and the multi-layer structured coating lie and the region in which the optical reflection facet and the multi-layer structured coating lie, so that the optical anti-counterfeiting component or the optical anti-counterfeiting product that includes the optical anti-counterfeiting component can be identified easily and has high anti-counterfeiting capability.

Abstract: Disclosed are an optical anti-counterfeiting element and an optical anti-counterfeiting product utilizing the same, the optical anti-counterfeiting element comprising: a substrate (2) having a first surface (31) and a second surface (32) that are opposed to each other, a sampling and synthesizing layer (21) on a first surface (31) of the substrate (2); and a micro-image layer (22) on a second surface (32) of the substrate (2), the micro-image layer (22) including a first region at least partially covered with a coating (221) and a second region comprising at least two sub-regions each at least partially covered with a color function layer (222, 223), the color function layers (222, 223) in respective sub-regions and the coating (221) in the first region have different color characteristics, respectively, and the micro-image layer (22) can be sampled and synthesized by the sampling and synthesizing layer (21) to form an image.
