EYE TRACKING USING COHERENCE-BASED MEASUREMENT

This abstract first appeared for US patent application 20240398224 titled 'EYE TRACKING USING COHERENCE-BASED MEASUREMENT

Original Abstract Submitted

various implementations disclosed herein include devices, systems, and methods that track a state of a user's eye (e.g., position/orientation, gaze direction accommodation, pupil dilation, etc.) using coherence-based measurement (e.g., optical coherence tomography (oct)). the coherence-based measurement may provide sub-surface information, e.g., depth, cross section, or a volumetric model of the eye, based on reflections/scattering of light (e.g., using relatively long wavelength light to penetrate into the eye tissue).
