ATOS Core Technology

Optics and electronics are integrated in a very small installation space. Its compact shape gives the sensor high stability and allows measurements to be taken in confined spaces. Depending on resolution requirements and measuring area sizes, the easy-to-handle sensor heads can be replaced easily via a quick release, without the need for recalibration.

Self-Monitoring System

The sensor recognizes changing ambient conditions during operation and can compensate these changes. To ensure the quality of the measuring data, the software of the sensor is continuously monitoring the calibration status, the transformation accuracy, environmental changes and part movements.

Triple Scan Principle

Together with both cameras, the projection unit operates according to the Triple Scan Principle. During the measurement, precise fringe patterns are projected onto the surface of the object and are recorded by two cameras and the projector unit. Thus, 3D surface points from three different ray intersections can be calculated.

Blue Light Technology

The projection unit of the ATOS Triple Scan system is based on Blue Light Technology. Since the sensor works with narrowband blue light, interfering ambient light can be filtered during image acquisition. Due to its powerful light source, short measuring times can be achieved.

Live Tracking & Part Positioning

In addition to the full-field scanning, ATOS Core 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 Core. This makes it easier to transfer the virtual alignment of components into reality. Tracking can used for example for targeted positioning of components on CNC processing machines or palettes for material allowance control. Further applications include the assembly analysis of molds and tools as well as the positioning and assembly of sand cores and mold halves. Tracking can also be used for online positioning of components in the nominal position or in a subassembly, such as in the Meisterbock & Cubing, as well the setting and positioning of fixtures and reference frames.

Optically Tracked Touch Probe

Many complex metrology applications require the combination of full-field and point based 3D measurement. The GOM Touch Probe is available as an add-on to the ATOS Core:

  • Full-field and point-based 3D measurement
  • Measurement of difficult to access areas
  • Direct comparison to CAD
  • Measurement of primitives
  • Quick measurement of individual points
  • 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 switching between surface and single point measurement and analysis.

User Calibrationt

As ATOS Core is delivered pre-calibrated and ready-to-scan, it requires low maintenance. The stereo camera set-up continuously monitors the calibration status. Should the ATOS Core become de-calibrated, the user is immediately informed. ATOS Core can then be quickly and easily recalibrated by the user or automatically with a robot. The sensor does not need to be sent to GOM or one of its partners to be recalibrated, the calibration can be freely carried out by users at any time.
