On the housing of the scanner unit there are placed at least four infrared emitters which are flashing all
three milliseconds. The sensor unit receives the infrared signals and can exactly define the 3D position of
the handheld scanner unit or touch probe, which are moved in the large working space of the 3D Creator.
By using a dynamic calibration the scanner and the 3D Creator are operating in the same coordinate
system. The scanner unit and the 3D Creator are synchronized with a joint trigger signal so each scanner
line is combined with the according X,Y,Z coordinates. These values can be directly transferred into one of
several possible application packages which are running with the 3D Creator.

The 3D Creator FreeScan system is build of the sensor and the control unit of the 3D Creator and a scanner unit which is assembled with actively flashing infrared emitters. Synchronisation is realized by a special trigger signal between the control unit and the scanner unit. The scanner unit and the control unit are both connected with USB line to the PC or Notebook. All application packages are running on the PC or Notebook. The system can additionally be used which the free movable touch probe.
