Abstract
A system for scanning or plotting a graphic image. The system deflects (10) a portion of the beam of light (18) by an amount dependent upon the value of a characteristic of a signal (12). A plurality of signals is generated (12), each having a different value of the characteristic. Portions of the beam are deflected along paths (15), such that the pixels created by one portion are disposed along one scan line, while pixels of the other portion are disposed along a successive scan line.
