Abstract
Techniques are described for enhanced eye tracking for display systems, such as augmented or virtual reality display systems. The display systems may include a light source configured to output light, a moveable diffractive grating configured to reflect light from the light source, the reflected light forming a scan pattern on the eye of the user, and light detectors to detect light reflected from the eye. The orientation of the diffractive grating can be moved such that the light reflected from the diffractive grating is scanned across the eye according to the scan pattern. Light intensity pattern(s) are obtained via the light detectors, with a light intensity pattern representing a light detector signal obtained by detecting light reflected by the eye as the light is scanned across the eye. One or more physiological characteristics and/or a rotation speed of the eye are determined based on detected light intensity pattern(s).
