| titleOfInvention | A method for multiplexing anti-counterfeiting shading patterns and space-frequency multiplexing metasurface images |
| abstract | The invention discloses a method for multiplexing an anti-counterfeiting shading pattern and a space-frequency multiplexing metasurface image. The method utilizes a metasurface having the function of a polarizer, which can regulate the polarization state and intensity of incident polarized light. Marius' theorem can obtain the display of two-channel nano-printed images, one of which is used to display a mixed image based on space-frequency multiplexing, which can extract different image information at different cutoff frequencies, so that the method can be Expanded to three-channel multiplexing. The invention provides a new information multiplexing method, and adding anti-counterfeiting shading patterns can be widely used in the fields of anti-counterfeiting of high-end products. |
