摘要
An optical imaging heads that produce a plurality of light spots on light sensitive media such as photographic film or printing plate. The optical head incorporates an array of multi-mode laser diodes as a light source, a Micro Light-Pipe Array (MLPA) as a beam-shaping element, means for reducing the divergence of the laser diode beam in the fast axis direction and means for imaging the laser diode emitters on a surface close to the micro light-pipe entrance aperture.
