A laser scanner is an industrial device used for precise, non-contact measurement and detection. It emits laser beams to capture detailed 3D surface data, enabling high-accuracy inspections, quality control, and dimensional analysis. Common applications include automated metrology, reverse engineering, and robotic guidance in manufacturing, automotive, and aerospace industries. Key features include fast scanning speeds, sub-millimeter accuracy, and compatibility with CAD software. Industrial-grade models are ruggedized for harsh environments, offering reliability in production lines and logistics (e.g., barcode scanning).
