ABSTRACT:
A method of scanning is disclosed in which an array of light sources is used to record an image on a light-sensitive recording medium. Each of the light sources is modulated in accordance with an information signal. Multiple passes of the array are made relative to the recording medium, and a set of raster lines is recorded in each pass. The raster lines of successive sets are interleaved to space the raster lines closer together than the spacing of the light sources in the array. In order to provide precise spacing of the raster lines, the array of light sources is advanced a constant distance between successive sets of raster lines.
