<p>The object is scanned by means of optoelectrical sensors of at least two different types, being on the one hand sensors (2, 3, 9) with coarse resolution for the measurement of all or large parts of the object and on the other hand sensors (4-8) with fine resolution for the detailed measurement of the object. By means of the sensors of the first-mentioned type are determined the presence and the position of any variations in quality which are of interest in this context. The nature of any such variations is then determined by the sensors of the other type.</p> |
