An optical sensor for measuring the distance and/or inclination of a surface, especially in relation to a reference plane, or for detecting the distance and/or a modification in the inclination of a surface. The invention is characterized in that a light spot is created on a detector by focusing a beam of light, which is collimated in a first direction, in a direction which is perpendicular to the first. The results in the appearance of a line focus along the first direction of the surface. The line focus is represented in a second direction on the detector. The beam of light which is reflected on the surface and collimated in the first direction is simultaneously focused onto the detector. The line focus is disposed in a perpendicular position with respect to the reflection plane which is covered by the incident and reflected light.
