Abstract
A method for detecting a gaze direction of an eye includes the steps of irradiating at least one wavelength-modulated laser beam onto an eye, detecting an optical path length of the emitted laser beam based on laser feedback interferometry of the emitted laser radiation with a backscattered radiation from the eye, detecting a Doppler shift of the emitted radiation and the backscattered radiation based on the laser feedback interferometry, detecting an eye velocity based on the Doppler shift, and detecting an eye movement of the eye based on the optical path length and the eye velocity.
