Industrial 3D Scanning Technology
The ATOS series of industrial non-contact structured blue light 3D scanners provide precision scans with detailed resolution at high speeds. ATOS is engineered with advanced hardware and intelligent software for repeatable accurate measurements with flexibility and process reliability.
ATOS solutions are used in many industries for the inspection of parts such as sheet metals, tools and dies, turbine blades, prototypes and injection-molded and pressure die-cast parts.
ATOS‘ proven stereo camera technique delivers, for each measurement, an over determined system of equations. The combination of the stereo camera technology with GOM's reference point system allows ATOS to guarantee process reliability by:
The GOM Touch Probe combines full-field and touch probe 3D measurement. The GOM Touch Probe allows quick measurement in difficult to access areas, comparison directly to CAD, measurement of primitives, quick measurement of individual points and online alignment.
ATOS and Touch Probe measurements are carried out with one system and are evaluated with one software package. No extra hardware or tracker is required, enabling quick measurement procedures and easy interchange between surface and single point measurement and analysis.

In addition to the full-field scanning, ATOS systems can also be employed for live measuring of movements and deviations. This tracking is based on the stereo camera principle in connection with the GOM reference point system. Single points as well as complete components geometries can be traced in space. The alignment or positional deviation of a component from the nominal position can and also be measured and tracked live by the ATOS. This makes it easier to transfer the virtual alignment of components into reality.
Precise fringe patterns are projected onto the surface of the object and are captured by two cameras based on the stereo camera principle. As the beam paths of both cameras and the projector are known in advance due to calibration, 3D coordinate points from three different ray intersections can be calculated. This triple scan principle offers advantages for measuring reflective surfaces and objects with indentations. The result is complete measuring data without holes or erratic points.
GOM’s projection technology works with narrow-band, blue light, which means that interfering ambient light can be filtered out during image acquisition. In addition, ATOS 5 is equipped with a Blue Light Equalizer, which increases the brightness of the light source by a factor of 1.5 and transmits uniform, non-coherent, speckle-free light to the projection unit. The Blue Light Equalizer of ATOS 5 is so powerful that even on unconventional surfaces short measuring times can be achieved and the precise coverage of complex geometries is possible.
The light processing of the ATOS 5X is extended by a Laser Light Compressor, which bundles several laser elements to generate an extremely bright light source on the based on laser light. The light, which is up to eight times brighter, is particularly resistant to ambient light influences and enables measuring areas of up to 1,000 mm and extremely short exposure times. This reduces the number of required scans, simplifies the measuring setup and shortens the measuring time.
ATOS Professional offers numerous additional functions for controlling GOM hardware and for generating accurate 3D surface data. This guarantees high process security at all times. The intuitive operating concept makes it possible to implement all measuring tasks easily and flexibly.
