The aim of the work is a comprehensive investigation and development of methods for creating reconfigurable diffractive elements and unique relief identifiers based on technologies of direct laser writing and local laser modification of surface layers. Within the framework of the project, primary attention will be devoted to the physical processes of microrelief formation under the action of coherent radiation, the optical principles of controlling the structure of the formed elements, and the algorithms for reproducing their optical characteristics. The project also envisages studying the possibilities of using such microstructures for the implementation of optical tags as unique identifiers intended for cryptographic protection, authentication, and anti-counterfeiting applications. The research will be carried out using methods of direct laser writing, physical optics, and comprehensive computer modeling of the processes of microstructure formation and readout. The expected results will contribute to the development of new technologies in the field of secure identification and long-term optical data recording, which is important for information security, protection of intellectual property, and high-technology industrial applications.
