As the only Polhemus distributor in the UK, Virtalis is poised to launch a new six-degrees-of-freedom tracking product line.
As the only Polhemus distributor in the UK, Virtalis is poised to launch a new six-degrees-of-freedom (DOF) tracking product line.
The Liberty Series represents a technological leap in state-of-the-art digital signal processor (DSP) electronics.
Liberty scans at 240Hz per sensor, giving immense speed.
Its graphical user interface (GUI) makes it intuitive, and its scalability and improved signal to noise ratios increase stability and resolution, providing consistently high quality data.
The combination of all these attributes places Liberty in pole position in the electromagnetic tracking technology field.
"With over a quarter century of experience, Polhemus holds and maintains the responsibility to drive the advancement of six DOF tracking technology", Andrew Connell, Technical Director at Virtalis said.
"The Liberty series is the first of a family of new products which undoubtedly will have a major impact on how users implement and apply electromagnetic tracking technology".
Each Liberty sensor is able to independently detect distortion within the environment, alerting the user to make appropriate changes if necessary.
Resolution is better than 0.001in and 0.01 degrees.
Absolute accuracy is better than 0.03in RMS for the x, y and z position and 0.15 degrees RMS for rotation.
Latency is less than 4ms for all sensors simultaneously.
Range is in excess of 5ft and can be substantially extended with the use of an optional transmitter.
The Polhemus Liberty series, joins the Fastrak and Isotrak II, in the company's stable of tracking products.
Polhemus' 3D position and orientation tracking, digitising, eye tracking and handheld three-dimensional scanners are in wide use in such areas as medical applications, university research, military training and simulation and computer-aided design.
