Optical sensor for measuring the distance and/or inclination of a surface, particularly relative to a reference plane, or for detecting the distance and/or change in inclination of a surface, characterized in that a light spot is generated on a detector in that a light beam that is collimated in a first direction is focused in a direction perpendicular to the first direction, so that a line focus is effected along the first direction on the surface and the line focus is imaged on the detector in the second direction and, at the same time, the beam that is reflected at the surface and collimated in the first direction is focused on the detector, wherein the line focus is perpendicular to the reflection plane defined by the impinging, reflected beam.
