Accuracy

 

    SMX/FARO systems measure objects that range in size from one to hundreds of meters with an accuracy of 25 microns (0.001 inches) at 5 meters. The Tracker follows the mirrored target over features, updating the position at a rate of 1,000 times per second. The abundance of data collected yields good statistical redundancy, permitting excellent accuracy and repeatability. The lower the accuracy requirements of a job, the faster the data can be taken.

   The key to optimum performance, is knowing in advance what the required accuracy needs will be for the measurement session. This will allow for the proper issues that effect accuracy to be addressed, and any special tooling to be made. Then  the Tracker technician can achieve the results you need, in an impressively short period of time.

Radial Speed / Resolution

The SMX/FARO Trackers provide a radial interferometer resolution of 0.16 microns (.6 micro inches). The target speed, regardless of resolution, is 6 meters per second (20 feet per second). Encoder angles are resolved to .25 arc seconds.

Weather Station

The Tracker Control Unit features an NIST traceable embedded barometer and thermistor that monitor temperature and barometric pressure and automatically adjust for measurement deviations caused by atmospheric conditions. This advanced feature is completely transparent to the user.
