Abstract:
An optical recording system for recording on a surface of a radiation sensitive material comprising:(a) a monolithic diode array having a plurality of individually addressable multimode laser diodes, each of said diodes comprising an emitting aperture having a short axis and an elongated axis and each of said diodes operative to receive information and to emit a radiation pattern according to said information; and (b) an optical subsystem having at least one optical element, operative to direct each of said radiation patterns from said diodes to the surface of said radiation sensitive material, â€ƒwherein said optical subsystem is configured to introduce astigmatism into said radiation patterns and to form, on the surface of said radiation sensitive material, an image of each of said emitting apertures that is substantially focused on its short axis and is blurred on its elongated axis, so as to record said information on the surface of said radiation sensitive material, while substantially avoiding revealing a near-field non-uniformity of said radiation patterns.
