<p>A system for obtaining a signature from a scan area on the surface of an article comprises: a signature generator that generates the signature from scattered coherent radiation detected from a plurality of points on the surface and includes a scan head comprising a coherent radiation source and photodetectors; a camera for capturing an image of the surface; a comparator that compares the captured image with a reference image to determine the location and orientation of the scan area; and a drive assembly that positions the scan head appropriately for generating a signature from the scan area in response to the determination of the location and orientation of the scan area.</p>
