Patent abstract
A system for tracking eye location is disclosed. Systems in accordance with the present invention include a scanner for sweeping a first optical signal across the surface of an eye, a detector for detecting a second optical signal reflected from the eye, and a detection circuit for determining a maximum intensity in the second optical signal. In operation, the scanner sweeps the first optical signal over the surface of the eye while the detection circuitry determines a plurality of intensity maxima in the second optical signal. The time between the intensity maxima during the sweep is indicative of the location of the cornea within the eye surface.
