  "textContent": "The sensor (10) has a light emitter (12) and a light receiver (36) imaging an object, and a distance measuring unit (42) determining distance between the sensor and the object. Magnification of the object is corrected by a scale correcting unit (44) in dependence of distance, and the light emitter comprises two light sources (14a, 14b) e.g. LED, whose illuminating region partly overlaps, so that a common lighting region is provided with location-dependant intensity differences on the object, and that the spacing measuring unit determines distance from the intensity differences.",
