Metasurface-Driven Adaptive Structured Light: Achieving Integrated Real-Time 3D Reconstruction and Forward Ranging in Multi-Scene.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 structured light with a central bright spot is generated within 2π space. By integrating a self-developed multimodal point cloud enhancement algorithm, a 3D reconstruction and forward ranging system adaptable to diverse scenarios has been successfully developed. This system achieves real-time 3D reconstruction and forward ranging at 30 fps without additional ranging modules. This technology not only transforms the hardware architecture of existing structured light systems and surpasses the limit of light emission angles but also overcomes the application constraints of traditional methods in diverse scenarios. It provides innovative technological support and solutions for the digital construction of tunnel engineering.
