The light radiated back from the surface of the component (5) is detected by a sensor. To improve such a method, only a rear region (19, 19′) of the surface of the component (5) is radiated with light from the light source (4, 4′) and/or only the light radiated back from a rear region (19, 19′) of the surface of the component (5) is detected by the sensor and/or evaluated by an evaluation device FIG. 3).
