FastSCAN was used in the Joint Mongolian-Smithsonian Deer Stone Project which included archaeological studies of "deer stones" and the ritual contexts in which they are found.

PATRIOT
 
PATRIOT is the leading cost-effective solution for 6 Degree-Of-Freedom motion tracking and 3D digitizing. Available with stand alone system electronics unit or compact PC drive bay configuration (see PATRIOT DB PDF link above), it's an expandable system that can accommodate up to two sensors, making it perfect for a wide array of applications. From head tracking, biomechanical analysis and computer graphics to cursor control and stereotaxic localization, PATRIOT delivers a sweet spot combination of performance and value.
 
Expandable, Versatile and Easy to Use
PATRIOT includes a system electronics unit (SEU), a power supply, one sensor and one source. The system's capabilities can be expanded by simply adding an additional sensor or an optional stylus. Measuring in at only 6.75 by 6.25 by 1.75 inches (LWH), the electronics unit is compact for easy installation in any environment. PATRIOT interfaces with the host computer via RS-232 or USB. It's fully compatible with Windows™ XP/Vista/Win7 (open-source application for Linux® also available). 

PATRIOT utilizes AC tracking technology, which has been perfected through multiple generations to deliver the industry's highest level of performance and reliability. The source and sensor contain electromagnetic coils enclosed in plastic shells. The source emits magnetic fields, which are detected by the sensor. The sensor's position and orientation are precisely measured as it is moved. Because the sensor is completely passive, it's safe for use in any application.

PATRIOT provides dynamic, real-time measurements of position (X, Y and Z Cartesian coordinates) and orientation (azimuth, elevation and roll). PATRIOT can update data continuously, discretely (point by point), or incrementally. With the optional stylus, trace the outline of a physical object or collect polygon facets and get pinpoint accuracy of unlimited X, Y and Z data points.

PATRIOT is designed for unrivaled ease-of-use. Within a few minutes after unpacking the box, the system will be up and running. Data can readily be output to third-party applications for custom functionality to meet virtually any need. The system is factory calibrated and never requires adjustment.
 
Low Latency, High Stability
PATRIOT is designed to deliver reliability in demanding real world applications. It offers low latency and high stability to ensure precise, uninterrupted tracking at all times. PATRIOT boasts an update rate of 60Hz per sensor and an operating range (radius) of five feet. 
 
Quiet and stable, the system is essentially unaffected by facility power grid fluctuations. Update rates are always maintained, because AC magnetics offer superior signal to noise ratios. Sophisticated digital signal processing helps provide optimal signal. In addition, adaptive filtering is available as a standard feature.

Advanced A/C Technology
Polhemus pioneered A/C motion tracking and has refined and perfected the technology through numerous generations. Unlike products based on pulsed D/C technology, Polhemus trackers are not negatively affected by the earth's magnetic field, power outlets or electric motors. Because A/C tracking is also more accurate and faster, it's clearly the superior choice. In fact, Polhemus originated pulsed D/C technology, but chose not to pursue it because of performance shortcomings.

There is no need to worry about maintaining a clear line-of-sight between the sensor and source. Unlike sonic or laser devices, PATRIOT is not affected by signal blocking and interference.
