Zusammenfassung:	A system tracks eye movement using optical coherence in a head mounted display. The system includes an illumination source configured to project low coherence interference light onto a portion of a user's eye. The system includes a scanning system to select an axial position within the illuminated portion of the user's eye. The system includes a detector configured to collect light reflected from the illuminated portion of the user's eye at the selected axial position, and the reflected light includes measurement data characterizing the illuminated portion of the user's eye. The system includes a controller configured to compare the measurement data with a trained baseline, and determine an eye position based the comparison.
