Abstract
Metasurface-based image encryption is becoming an increasingly prevalent trend in optical security; yet, limited attention has been directed towards metasurface-based image authentication. Here, we present a holographically marked metasurface for multi-user authentication based on polarization multiplexing technology. Through embedding a holographic marker in the metasurface via a different polarization channel, it simplifies the distinction between different metasurfaces, while simultaneously achieving multi-user authentication. In the authentication process, only by applying the correct authentication keys to the metasurface can the verifiable images be reconstructed. Computer simulation results confirm the feasibility and security of the proposed metasurface-based security approach.
期刊介绍：
Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods.
Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following:
-Optical Metrology-
Optical Methods for 3D visualization and virtual engineering-
Optical Techniques for Microsystems-
Imaging, Microscopy and Adaptive Optics-
Computational Imaging-
Laser methods in manufacturing-
Integrated optical and photonic sensors-
Optics and Photonics in Life Science-
Hyperspectral and spectroscopic methods-
Infrared and Terahertz techniques
