Abstract
An eye tracking system for a head-mounted device determines depth characteristics of an eye in an eyebox region. The eye tracking system includes a detector array, a scanning mirror, and a light source. The detector array is oriented on the head-mounted device to receive reflected light from an eyebox region of the head-mounted device. The scanning mirror is optically coupled between the eyebox region and the detector array. The scanning mirror is configured to rotate to direct the reflected light from a plurality of locations within the eyebox region to the detector array. The light source configured to provide pulses of light to illuminate at least part of the eyebox region.
