Structured light projection with metasurfaces a A typical structured light projector consisting of a light source, a collimator lens, and a diffractive optical element (DOE) [102, 103], b All-silicon nanorod-based Dammann gratings for splitting incident beam into spot arrays [122], c Full-space cloud of random points with a scrambling metasurface [123], d Complex amplitude modulation of the selective diffraction with a dielectric metasurface [124], and e Metasurface for structured light projection with 120° field of view [125]
