Abstract
A six degree-of-freedom optical tracker system includes LEDs that are mounted on a structure, and are each configured to emit light. An LED controller is coupled to the LEDs and supplies drive current to each of the LEDs in a manner that causes the LEDs to sequentially and individually emit light. A single position sensing device that is spaced apart from each of the LEDs receives the light emitted from each of the LEDs and supplies position data for each LED. A processor receives the position data and determines the position and orientation of the structure relative to the single position sensing device.
