Single pixel imaging based on large capacity spatial multiplexing metasurface

Abstract Single pixel imaging as an alternative to traditional methods, has attracted extensive attention in various research fields. Metasurfaces with subwavelength unit cells and compact footprint can be used a substitute for optical elements. In this work, we propose single scheme based on metasurface composed of photon sieves, where spatial modulation is realized through shifting. Spatial multiplexing capability demonstrated by shifting mode, which obtain more patterns limited space greatly increase the mask capacity. Benefited from simple structure easy manufacture large capacity manufactured. Meanwhile, metasurfaces simplify system, leading system miniaturization integration. addition, numerical experiments prove that our proposal operate at range entire visible light near-infrared light. Such provides new way would applied microscopic imaging, dynamic hyperspectral so on.
