Polhemus Liberty Tracking System
The Polhemus Liberty is a magnetic system offering 6 Degrees of Freedom. In addition, it can track with 16 sensors simultaneously at a frequency of 240 Hz each! With its 240 Hz sampling rate, the tracker continues to impress. It can deliver full 6DOF data with virtually no latency (at less than 4ms).
Then, to meet the most complex applications, the system is equipped with distortion detection, a standard for ensuring high quality data. Finally, the system comes standard with four sensor channels and optional upgrades to 8, 12 or 16. You can also add a Polhemus stylus for 3D pointing or feature positioning.
