Metasurface-Driven Adaptive Structured Light: Achieving Integrated Real-Time 3D Reconstruction and Forward Ranging in Multi-Scene.

ABSTRACT: In structured light-based three-dimensional (3D) reconstruction technology, normal and grazing emission beams hold significant application value due to their stable axial propagation characteristics and anti-distortion advantages. However, current systems face two major technical bottlenecks. First, traditional grazing emission beams depend on the precise assembly of complex optical components, which compromises reliability and impedes miniaturization. Second, the physical constraints of light field transmission make it challenging to generate both modes simultaneously within a single system. This study exploits the light waves modulation capabilities of metasurface to achieve the simultaneous generation of normal and grazing emission dual-mode beams. Specifically, an adaptive closed-line
