Controlling the polarization of light has been interest for various applications in laser materials processing, display systems, and spectroscopy among others. Despite great advancements, level control over using naturally birefringent liquid crystals is still limited. In recent years, dielectric metasurfaces have enabled an unprecedented phase light. Here, we demonstrate vectorial holograms with almost arbitrary patterns structurally metasurfaces. Using a modified Gerchberg-Saxton algorithm converting red–green–blue data color images to Stokes parameters, show that demonstrated can store project image state monochromatic hologram. addition enhanced security storage capacity, believe developed concepts methods will spur new advanced structured illumination techniques, more generally, whenever complex pattern required.
