Apparatus for gaze tracking an eye utilizing short coherence length interferometry, also known as optical coherence tomography ("OCT"). An embodiment of the present invention is an apparatus for gaze tracking an eye which includes: (a) an optical coherence tomography (OCT) apparatus; (b) a scanning apparatus for scanning across a predetermined portion of the eye with optical output from the OCT apparatus; (c) an analysis apparatus for analyzing detection signals output from the OCT apparatus to determine a location of a feature of the eye; (d) an illumination apparatus for producing a reflection of radiation from a cornea of the eye (corneal reflex); (e) a detection apparatus for determining a location of the corneal reflex; and (f) the analysis apparatus further includes an apparatus which is responsive to the location of the feature and to the location of the corneal reflex for gaze tracking.
