Abstract: Technologies are described herein for an eye tracking that may be employed by devices and systems such as head mount display (HMD) devices. Light that is reflected from a user's eye may be specular or scattered. The specular light has an intensity or magnitude that may saturate the electronics. The presently disclosed techniques mitigate saturation by generating detected signals from an optical detector, evaluating the signal levels for the detected signal, and selectively gating the detected signals that have saturated. The remaining scattered signals can be combined to achieve a combined signal that can be converted into a digital signal without saturating the electronics, which can then be processed to form an image of the eye for identification purposes, for tracking eye movement, and for other uses. The described technologies provide a clear image without ambient light reflections or specular light interfering with the image.
