Abstract

The invention relates to a sensor for measuring the surface of an object, having a contrasting unit (3) for projecting a pattern onto the surface of the object, and having a camera (4) for recording of the pattern projected onto the surface of the object, in which the contrasting unit (3) has an LED projector (5). To achieve high precision and great robustness, the camera (4) and the LED projector (5) are located in the longitudinal direction. In addition, respective deflecting mirrors (8, 11) are assigned to the camera (4) and the LED projector (5) and are located on opposite ends, in the longitudinal direction of the sensor (1), of the housing (2) of the sensor (1).
