Abstract
An optical device for determining a pupil position of an eye. The optical device includes a laser, first and second photodetectors, a beam deflection device, and a control unit. The optical device guides light generated by the laser at least partially as illumination light via an illumination beam path to the beam deflection device and illuminates illumination points on the eye/eye environment using the illumination light, during the illumination of a first portion of the illumination points, measures using the first photodetector a laser power of the laser when illuminating the illumination points and/or detects using the first photodetector illumination light reflected at a boundary surface of the eye/eye environment and entering the illumination beam path via the beam deflection device, and, during the illumination of a second portion of the illumination points, detects illumination light scattered on the eye/eye environment using the second photodetector.
