Abstract

A sensor device (100), for measuring a surface (101), includes a lighting device (103) emitting a light beam (105); an optical device (107) splitting the light beam (105) into partial light beams (109, 111), and emitting the first partial light beam (109) toward a first surface area (113) and emitting the second partial light beam (111) toward a second surface area (115). A light sensor (117) is configured to receive a first surface area reflection (109-1) of the first partial light beam (109) and a second surface area reflection (111-1) of the second partial light beam (111). A processor (119) is configured to detect a distance of the first surface area (113) and of the second surface area (115) to the sensor device (100) based on a position of the first partial light beam reflection (109-1) and the second partial light beam reflection (111-1) on the light sensor (117).
