    摘要: A method and apparatus that provide multichannel imaging and that allow using diffraction-limited optics. The imaging apparatus includes a laser beam source to generate single-mode laser beam of energy, a multichannel spatial light modulator (SLM) accepting a plurality of modulating signals, and a beam multiplier between the radiation source and the SLM. The beam multiplier accepts the beam generated by the source and generates from that beam a plurality of beams directed onto the SLM. The beams from the beam multiplier illuminate the active region of the SLM such that the SLM generates a plurality of modulated beams modulated according to the modulating signals. The apparatus further includes an optical subsystem located between the SLM and an imaging plane that includes at least one optical element to focus the modulated beams onto an imaging plane. A recording medium sensitive to imaging radiation from the source is placed at the imaging plane. The recording medium is capable of being permanently marked in response to incidence of such imaging radiation. The beams generated by the SLM are each substantially a single-mode beam such that the first optical subsystem may be designed using diffraction-limited optics.

    摘要: A xerographic print engine employs a photoreceptor with an image receiving surface, a printhead for directing light to the photoreceptor to produce thereon a latent image, and a developer for converting the latent image to a printable image to be transferred from the photoreceptor to a print medium during a relative motion between the photoreceptor and the print medium. The printhead has light emitting diodes (84) disposed in plural rows (82,86) arranged alongside each other on a substrate which also supports driver circuitry connecting with imaging electronics for activating individual ones of the diodes. An optical element (lens 30) focuses light of the diodes onto a row of the latent image, the focussing being accomplished concurrently for individual ones of the diodes located in a plurality of the rows.

    摘要: Disclosed is an image forming apparatus (13) which provides an image of an excellent quality which has a less variation in resolution and suppressed linear irregularity. A rod lens array (24) includes two rows of rod lenses (25) stacked one on the other. An LED array (23) is offset by a predetermined offset amount (Y) from a plane (C) passing the median position between the first row of rod lenses and the second row of rod lenses. This structure can realize an LED printer head which reduces a variation in the resolution of the rod lens array, thereby suppressing linear irregularity, and can thus provide an image having an excellent quality.

    摘要: An optical write-in head for obtaining a clear image even in printing at a relatively high recording density without generating strip-like irregularities in most cases. The optical write-in head applies light carrying image information to a photosensitive substance. The optical write-in head includes an array light source (23) having a plurality of dot light sources, each of which selectively emits the light corresponding to the image information, and a lens array (24) facing the array light source. The lens array (24) has a plurality of lens elements (25) which corresponds to the plurality of dot light sources respectively. An angular aperture θ of each of the lens elements (25) is set in a range of about 14° to 18°.

    摘要: Es wird eine Einrichtung zur Bebilderung einer Druckform mit einem Array von Lichtquellen einer Abbildungsoptik zur Erzeugung von (n x m) Bildpunkten auf einer Druckform vorgeschlagen, welche sich dadurch auszeichnet, dass das Array von Lichtquellen ein Array von unabhängig voneinander ansteuerbaren VCSEL-Lichtquellen umfasst. Ein bestimmter Bildpunkt auf der Druckform kann durch die Zusammenführung des in einem Teilarray der VCSEL-Lichtquellen emittierten Lichtes entstehen. Aufgrund der vorteilhaften Strahleigenschaften der VCSEL-Lichtquellen, wie beispielsweise der geringen Divergenz und des geringen Astigmatismus, ist die Einrichtung zur Bebilderung von Druckformen besonders vorteilhaft zum Einsatz in einem Druckformbelicher oder einem Druckwerk geeignet.
