ABSTRACT:
Laser beams corresponding to an image are directed through an afocal optical system such that chief rays of the laser beams outgoing from the system are substantially perpendicular to a recording surface and such that beam waists of the laser beams are approximately located at the recording surface. Thus, the image can be recorded on the recording surface with high picture quality.
