Abstract

Multibeam laser triangulation allows measuring different object regions simultaneously with short measuring times and a high dynamic range. This paper describes the methodological approach of multibeam laser triangulation, online measuring systems based on this concept and various industrial applications. For multibeam laser triangulation up to more than 120 laser beams are used to simultaneously measure geometric features of moving products such as e.g. the thickness, profile or surface topology.

多光束激光三角测量用于生产线运动物体几何特征的测量
多光束激光三角测量可以同时测量不同的目标区域,测量时间短,动态范围大。本文介绍了多光束激光三角测量的方法方法、基于该概念的在线测量系统以及各种工业应用。对于多光束激光三角测量,最多可使用120多个激光束同时测量移动产品的几何特征,例如厚度,轮廓或表面拓扑结构。
