Abstract
A raster output scanning system is disclosed which utilizes a single light source, an electro-optical device and a beam-splitter to generate two partially overlapping light beams in order to scan one scan line in which the width of the scan line can be adjusted electronically. The two partially overlapping light beams in effect generate a resulting light beam. By changing the polarization factor of the electro-optical device, the intensities of the two light beams can be modified which in turn will change the width of the resulting light beam and as a result the spot size changes. By changing the spot size, the width of the scan line can be adjusted. Also, by changing the polarization factor, the position of the resulting light beam can be changed.
