Abstract

An optical device for determining a distance of a measurement object includes a LIDAR unit and a light sensor. The LIDAR unit has an illumination device to illuminate the measurement object and a measurement channel to detect a measurement beam reflected from the measurement object and to generate a LIDAR measurement signal. The light sensor has an optical source with a mode-locked laser to generate first and second frequency comb signals and splits the first frequency comb signal into a first measurement signal and a first reference signal and to illuminate the measurement object with the first measurement signal. The light sensor splits the second frequency comb signal into a second measurement signal and a second reference signal. An evaluation unit determines first distance information, evaluates signals detected by a measurement detector and a reference detector, generates a frequency spectrum, and determines second distance information of the measurement object.
