Optical Metrology Basics: Triangulation

Triangulation is a trigonometric method to determine the distance between a reference point and a point of interest by aiming at the target from two different positions. In a so-called triangulation sensor this principle is put into practice and utilized for optical metrology: a laser beam is directed onto a surface at a well-defined angle of incidence, and the spot is picked up at a different angle and imaged onto a detector array. Combined with a scanner or a linear drive, the complete surface of the object may be probed and can be depicted as a point cloud in three-dimensional space. more24.09.2010

Quality Assurance of Chassis Parts

The SAL3D library from the Spanish software company, Aqsense, guarantees quick and precise capture of three-dimensional objects using 3D point clouds and therefore enables the comparison of body and chassis parts with a reference model directly after they leave the stamping tool to ensure optimal quality management. more28.06.2010

Tools for True 3D Point Cloud Acquisition

SAL3D provides easy-to-use, accurate and robust tools for true 3D point cloud acquisition and processing. For easy 2D integration, SAL3D provides ZMap, a flat representation of point clouds, which is a grey level image of floating point values created out of a SAL3D Cloud of Points. The ZMap features include pure proportional relationships between the image coordinates and the metric coordinates. more04.06.2010

Optical Measurement of Gear Teeth

Profile scanners (model scanCONTROL 2800-25) from Ortenburg-based sensor specialist Micro-Epsilon are able to generate digital 3D images of gear teeth and can be used to measure the run-out characteristics of gear shafts with plug-in toothing, bevel gears with hypoid toothing and similar axial components. more26.03.2010
