Abstract

An optical system for monitoring a vehicle driver's eye gaze includes a first illumination source and a second illumination source for emitting light towards the driver's eye, a lens, and an image sensor for detecting an image, wherein the lens is configured to direct light reflected by the driver's eye to the image sensor, and wherein a distance between the second illumination source and an optical axis of the lens is larger than a distance between the first illumination source and the optical axis. Further, a method for monitoring a vehicle driver's eye gaze with an optical system is disclosed.
