Liberty
A quantum leap in 6 Degree-Of-Freedom motion tracking technology, LIBERTY is the fastest and most accurate electromagnetic motion tracker available. With scalable support for up to 16 sensors, it is the indisputable forerunner in tracking technology. State-of-the-art digital signal processor (DSP) electronics, an intuitive graphical user interface (GUI) and a host of the most advanced technical features available make LIBERTY the professionals choice hands-down.
Unprecedented Speed, Stability and Resolution
Exclusive advancements in digital signal processor technology have enabled Polhemus to develop the worlds fastest tracker. LIBERTY tracks objects at a speed of 240 updates per second. Regardless of how many sensors are in use, the update rate remains constant, with LIBERTY outputting a clean data stream. For applications requiring less data, LIBERTY also has 120Hz update rate.
LIBERTYs blazingly fast 240Hz update rate makes it the perfect system for tracking high-speed events such as a golf swing or an athletes fast-paced movement. For virtual reality applications, LIBERTY performs real time head and body tracking. With virtually no latency, LIBERTY is the highest quality solution for military and simulation applications.
LIBERTYs DSP technology works in conjunction with the systems A/C magnetics to deliver improved signal-to-noise ratios. Increased range, stability and resolution are realized. LIBERTY offers remarkable accuracy of .03 RMS for X, Y and Z position and .15° RMS for orientation.
Designed for Ease of Use and Power
LIBERTY includes a streamlined with a GUI for Microsoft Windows®and intuitive user interface that is stocked with useful tools. Four independent user-definable profiles allow setting system parameters such as filtering, output formats, coordinate rotations and more. This valuable feature makes LIBERTY the preeminent tracker for accommodating multiple users or applications. An integrated motion box provides navigable points of view for visualisation and is also capable of displaying text data. Additional features include data recording and playback, plus rapid data exporting via Microsoft™ Named Pipe.
Polhemus understands that creating groundbreaking solutions requires the right tools. That is why LIBERTY includes a comprehensive and straightforward software developer kit (SDK). The SDK features API libraries that facilitate easy integration into custom applications.
LIBERTY connects to any PC via an RS-232 or USB connection. Within moments after unpacking the LIBERTY system, it will be up and running. LIBERTYs environmental calibration software allows rapid calibration.
Two Systems in One
The optional stylus expands LIBERTYs already robust capabilities by converting it into a 3D digitizer. With the stylus, you can collect dimensions of artifacts, archaeological items and museum sculptures, or compile measurements of anatomical features, body volumes, joint relationships or body contours. Capturing data with the ergonomically designed stylus is as simple as pressing a button.
Scalable to Meet Your Needs
Two different base LIBERTY systems are available to meet your needs and budget. The LIBERTY 240/8 system includes four sensor channels. Adding a circuit board to its chassis expands the system to 8 sensor channels. The LIBERTY 240/16 system also natively includes four sensor channels, but can be upgraded to 8, 12 or 16 channels within the same chassis.
LIBERTY includes a system electronics unit (SEU), one sensor and one source. Options such as additional sensors, a longer range source and a stylus are available.
