Metasurfaces have very wide application such as beam deflection, holographic images, polarization generation, tunable meta-devices, sensing, achromatic metalens [1] and pixel-level full-color routing [2][3]. Metalens have great ability in light focusing and can be tailored to exhibit varied functionalities in ultrathin optical applications. A metalens is realized by using integrated-resonant unit elements whose geometric phase are combined with phase compensation from integrated-resonant unit elements. In this work, we use metalens array to project a focused light spots array which has potential in the structure light application.
