Industrial optical 3D metrology

The 3D coordinate measuring machines capture full-surface, detailed quality information of a component in the shortest possible time. Thus, optical metrology is used worldwide for dimensional quality assurance, especially of plastic, cast and sheet metal parts from the automotive, aerospace or consumer goods industries. The 3D data provides a "digital twin" that can be used for further analysis or reverse engineering. Other applications also exist in more unusual areas, such as forensic science or art.

The origin of GOM's measurement technology was in the automotive industry in quality management. With these sensors it is possible to scan and evaluate everything from the smallest parts, which are no larger than 1 cm, to entire car bodies. In this way, the dimensional quality of the products can be ensured throughout the entire production process.

Overview of the various applications of GOM systems using an injection molding process chain as an example

Bruker Alicona

The core competence of Alicona products is the measurement of dimension, position, form and roughness in the fields of production metrology and production automation, prototype development as well as classical quality assurance. Based on the technology of focus variation, our measurement systems close a gap between classical coordinate metrology and surface metrology, as users can measure both GD&T features and roughness parameters robustly, accurately, traceably and with high repeatability with only one optical sensor.


GOM's optical fringe light sensors project precise fringe patterns onto the surface of the component and is captured by two cameras using the stereo camera principle. Since the beam paths of both cameras and the projector are calibrated in advance, 3D coordinate points can be calculated from the three different beam sections. This triple scan principle offers advantages when measuring reflective surfaces and undercut objects. The result is complete measurement data without holes or erroneous points.

An ATOS sensor represents a self-monitoring system the sensor software continuously controls the status of the calibration, the transformation accuracy as well as environmental changes and component movements to ensure the measurement quality.
