ABSTRACT:
A system for scanning objects is disclosed. The system consists of a light source, a spatial light modulator, and appropriate optics for directing the light from the source to the spatial light modulator and to the object to be scanned. Individual elements upon the modulator are activated to reflect those pixels' width of the light to the object. A detector is mounted such as to receive reflections from the object to be processed. The system can be hand-held, mounted into a counter, or used in other applications such as edge detector scanners.
