摘要： Disclosed are a metasurface-based structured light 3D imaging system and method, which use a metasurface-based control device to realize high-quality control of a laser beam, use a MEMS micromirror to scan and project the laser beam, and realize high-precision reconstruction of 3D information of the surface of an object together with related structured light design and demodulation methods. The invention realizes fine control of a structured light, improves the quality of a structured light field, reduces laser speckles and improves power, thus improving 3D imaging precision and robustness.
