Abstract
Aspects of the present disclosure describe systems and methods for eye-tracking by steering a scan beam in a two-dimensional pattern over a scan region on the eye and detecting light reflected from a plurality of reflection points in the scan region at an angle-sensitive detector. The three-dimensional location of each reflection point is determined by triangulating the instantaneous propagation directions of the scan beam and the reflected signal from that reflection point. Gaze direction for the eye is determined from the locations of the reflection points in three-dimensional space.
