Abstract
A tracking apparatus includes a photosensor. The apparatus includes only a single, physically compact, optical pattern emitting base station. The apparatus includes a computer that tracks the photosensor to sub-millimeter accuracy using the optical pattern emitted by the base station. Alternatively, the computer determines angular position of the photosensor relative to the base station to a finer resolution than the size of an aperture of the photosensor from the light emitted by the base station. A method for tracking.

A tracking apparatus comprising:
- a photosensor;
- only a single, physically compact, optical pattern emitting base station;
- and
- a computer that tracks the photosensor to sub-millimeter accuracy using the optical pattern emitted by the base station.
A tracking apparatus comprising:
- a photosenser having an aperature;
- a light emitting base station;
- and
- a computer that determines angular position of the photosensor relative to the base station to a finer resolution than the size of the aperture of the photosensor from the light emitted by the base station.
A method for tracking comprising the steps of:
- a photosensor;
- emitting an optical pattern with only a single, physically compact base station. and
- tracking a photosensor with a computer to sub-millimeter accuracy using the optical pattern emitted by the base station.
A method for tracking comprising the steps of:
