Abstract
A spatial tracking system tracks movements of sources of radiated energy. In the one embodiment of the invention, three sensor sets are included each containing a pair of sensors. Movements of a single radiation source with a radially symmetric emission pattern is tracked in up to six dimensions; X, Y, Z, yaw, pitch and radiation intensity. Sources with different radiation ranges or types are tracked at the same time using sensors tuned to the different radiation ranges or types. The sensor sets may include more than two sensors which increases the spatial range monitored and increases tracking accuracy and optionally include sensors tuned to different radiation sources, such as light of different wavelengths. Individual sensors can be included with the sensor sets which increase the rotational range of the system beyond the range for translation tracking.
