ABSTRACT:
An integrated laser scanning system for scanning a modulated beam across an image surface, which may be a receptor on which the image is scanned, is provided by a rigid housing having a central plate and walls which define a plurality of cells on opposite sides of the central plate, some of which may extend through the central plate. A deflector, preferably having a rotatable hologon, a laser and optical components, including an assembly of components for processing and modulating the laser beam, are mounted in different ones of the cells and define a beam path which is folded and extends in one direction over the central plate and in an opposite direction out of the housing toward the image surface.
