Original Abstract Submitted
methods, systems, and apparatuses for eye tracking in a near-eye display device are described. in one aspect, an eye tracking system has an array of vertical cavity surface-emitting lasers (vcsels) with different groupings of vcsels within the array providing structured light with different polarization states such that the structured light projected onto the user's eye has (i) a spatially varying and/or temporally-varying intensity profile and/or (ii) a spatially varying and/or temporally-varying polarization profile. in another aspect, an eye tracking system includes a light source, an image sensor, and a controller which controls the image sensor to capture series of images of light reflections from the eye when the eye is stationary, determines blood flow characteristics using pattern changes in the captured series of images, and performs user authentication and/or liveness detection based on the detected blood flow characteristics.
