Time-sequential color code division multiplexing holographic display with metasurface

Color metasurface holograms are powerful and versatile platforms for modulating the amplitude, phase, polarization, other properties of light at multiple operating wavelengths. However, current color holography can only realize static manipulation. In this study, we propose demonstrate a multiplexing technique combined with multiwavelength code-division (CDM) to dynamic Multicolor code references utilized record information within single increase capacity security anti-cracks. A total 48 monochrome images consisting pure characters multilevel video frames were reconstructed in dual polarization channels birefringent exhibit high density, was displayed via sequential illumination corresponding patterns verify ability Our approach demonstrates significant application potential optical data storage, encryption, multiwavelength-versatile diffractive elements, stimulated emission depletion microscopy.
