ABSTRACT:
A multiple diode laser ROS scanning system is modified to eliminate the need for buffering scan lines so that they can be brought into the required adjacent lines at a photosensitive surface. The wavelength of the diode outputs are selected such that each diode differs from the other within a selected range. The beams are collimated and directed through a dispersive element such as a prism which is positioned so as to cause the beams to converge towards each other. After reflection from a reflective facet surface of a polygon, the beams are swept across the surface of an image media as adjacent scan lines.
