Abstract
Profilometers for industrial metrology and other applications are described. A line is projected on a surface to be profiled. The line is scanned to build a three dimensional point cloud allowing the three-dimensional (3D) profile of the surface to be determined. In some embodiments, the line is projected by a laser system. In other embodiments, the line is projected by a digital micromirror device (DMD). In still further embodiments, multiple lines, or other patterns are projected.
