Eye-Tracking System and Method Therefor |
摘要 |
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. |

1. A system for estimating the corneal vector of an eye, the system comprising:
a first source operative for providing a first optical signal, the first optical signal being characterized by a far-field pattern having a global intensity maximum; a first scanner operative for scanning the first optical signal within a scan region on the surface of the eye, the scan region including a surface feature of the eye; a first detector that is a discrete detector, the first detector being operative for providing a first electrical signal based on a second optical signal that includes a portion of the first optical signal reflected from at least a portion of the scan region; and a detection circuit operative for determining at least one maximum in the first electrical signal. |
