Optical distortions araising from predeflection focusing are analyzed from the point of view of laser character generators. It is shown that distortions can be kept below an acceptable limit. The advantage of multi-beam recording is analyzed and the principles of operation of a new multi-beam acousto-optic modulator are described. Using this modulator a simple laser character generator has been developed for a line printer which can work at 12,000 1pm speed.
