Polhemus Liberty


The fastest, most accurate, scalable electromagnetic tracker available, LIBERTY™ represents a quantum leap in new technology with up to 16 Sensors.

State-of-the-art Digital Signal  Processor (DSP) electronics make it the perfect real-time solution for six degree-of-freedom needs. LIBERTY has speed, ease-of-use via an intuitive Graphical User Interface (GUI), scalability, distortion sensing and improved signal to noise ratios which increase stability and resolution while providing consistent high quality data.

The Forerunner in Tracking Technology

LIBERTY incorporates an unprecedented speed of 240 updates per second per sensor,
the ability to upgrade from four sensor channels to eight or up to sixteen sensors by the addition of further circuit to the Liberty 240/16 boards and detection distortion, all the while providing the most accurate and consistent data. With the addition of the Polhemus Stylus, LIBERTY becomes a highly accurate 3D digitizer.

Easy, Intuitive User Interface

LIBERTY comes standard with Windows 2000/XP GUI and a comprehensive, easy to use
Software Developers Kit (SDK). The GUI allows four independent user definable profiles
for setting system parameters such as filtering, output formats, coordinate rotations and many
more. This is a valuable feature for multiple applications or users. For visualization, an
integrated motion box provides navigable points of view and can include text data. Additional
features include a data record/playback component, plus the capability to quickly export data
via Microsoft® “Named Pipe.”


A/C Magnetics:

Increases Stability, Resolution, Speed and Range

Incorporating state of the art Digital Signal Processor (DSP) electronics in concert with A/C
magnetics provides the user with improved signal to noise ratios which increase range,
stability, resolution and speed. The system is essentially unaffected by facility power grids,
and update rates are always maintained, keeping up with the voluminous rate of tracking data
