1. A method for imaging the characteristics of an object by means of a measuring system, in which at least one of the measuring system and/or the object is moved in relation to one another in a predefined direction of movement, the object being moved in relation to the measuring system, in which method the object is illuminated by means of incident light, which has limited extension in the direction of movement, and light reflected from the object is detected by means of an imaging sensor arranged on the same side of the object as the incident light, the image-processing sensor converting the detected light into electrical charges, according to which a digital representation of the object is created, wherein the light is made to strike the object at a predetermined distance from the imaging sensor viewed in the direction of movement of the object, and that information on the geometric profile of the object and information on the light scatter in a predetermined area around the said profile is simultaneously read out from the digital representation.
