Anti-Counterfeiting Element

An anti-counterfeiting element, comprising:

• a substrate;
• a reflecting curved mirror, a plurality of reflecting curved mirrors are provided, and the plurality of reflecting curved mirrors are arranged on a side surface of the substrate in an array;
• a micro graphic-text structure, at least part of the plurality of reflecting curved mirrors is provided with the independent micro graphic-text structure, the micro graphic-text structure is divided into a plurality of micro graphic-text areas from a central position to an edge position of the substrate, using a period of the reflecting curved mirror as a unit, and a duty ratio of a micro graphic-text area at the central position of the substrate is larger than a duty ratio of a micro graphic-text area at the edge position of the substrate;
• the reflecting curved mirror displays as a three-dimensional pattern with depth of field after sampling and synthesizing with the micro graphic-text structure having a coupling effect with it, and the three-dimensional pattern at least partially suspends on a side, away from the substrate, of the reflecting curved mirror;
• and a minimum unit radian of each reflecting curved mirror having the micro graphic-text structure corresponds to a projection angle, so that only a side surface of the three-dimensional pattern is able to be seen at an angle on the side, away from the substrate, of the reflecting curved mirror.
