Abstract

A range finder for determining at least one geometric information about at least one object is proposed that includes at least one illumination source adapted to generate at least one illumination pattern, wherein the illumination source is adapted to illuminate the object with the illumination pattern under an angle of inclination; at least one optical sensor having at least one light sensitive area, wherein the optical sensor is designed to generate at least one image matrix in response to an illumination of its light sensitive area by at least one reflection pattern originating from the object; at least one evaluation device being configured for determining the geometric information about the object from the reflection pattern by evaluating the image matrix assuming at least one geometrical constellation to be present in the reflection pattern.
