Abstract
In the invention, a light beam is scanned along a surface bearing data, such as a serial number. Reflected light is measured and processed for character recognition. The invention wobbles or dithers the light beam during the scan, and takes reflectivity measurements several times within a region on the surface, the region being called a pixel. This procedure enhances the reflectivity signature of edges, thus improving the ability to recognize characters.
