Abstract

A high density surface emitting semiconductor LED or laser array is coupled with a driver circuit substrate for modulating the light emitted from the array. This modulated light is imaged by optical means onto a photosensitive recording medium of an opto-electronic line printer. The imaging optical means can be either a single or multiple lens system.
