摘要： Die Erfindung befaßt sich mit dem Problem der Ju stierung der optisch wirksamen Systeme zur insbesondere zeilenweisen Ausgabe von Bildinformationen einer elek trooptischen Vorrichtung für Faksimile-Schreibeinrichtun gen, Fernkopierer etc. Sie besteht aus einem elektrisch steuerbaren elektrooptischen Substrat aus lichtdurchläs sigem elektrooptischem Material, wobei der optische Effekt durch Anlegen einer Spannung zwischen zwei auf dem Substrat benachbart angeordneten Steuerelektroden ge steuert wird. Erfindungsgemäß ist das Substrat (1) in einem rahmenartigen Gehäuse (17) senkrecht zur Längserstrek kung justierbar angeordnet. Zur Einstrahlung des Lichtes von einer Lichtquelle (37) her ist ein Licht-Querschnitts wandler (36) vorgesehen, der mittels eines Kreuzsupports in zwei Richtungen, senkrecht zueinander, verschiebbar angeordnet ist. Hierdurch können die Lichtzeichen des Sub strats (1) und die Lichtzeile des Licht-Querschnittswandlers (36) genau parallel zueinander justiert werden.

摘要： A circuit is disclosed for correcting the write power of a laser raster output scanner as it scans across a write drum (15). During calibration, a piece of glass (25) reflects part of the beam into a photo-multiplier tube (16), the output of which is converted into a digital signal. This is compared with a reference signal. The difference for each segment of the scan is stored in RAM and also is converted back to an analog signal to modulate an acousto-optic modulator in the laser optics to correct the write power. After the system has settled to a point where the write power at the drum does not vary across the scan, the glass may be removed, and the system thereafter operates using the correction signals stored in RAM.

摘要： A printing system employs a rotating drum for carrying a photosensitive printing medium in the form of a discontinuous sheet, there being a clamp carried by the drum and rotating therewith for holding ends of the sheet to secure the sheet to the drum. The system includes a print head having a laser beam which is spatially and temporally modulated for gray-scale printing of individual pixels of an image. The head is scanned parallel to an axis of the drum. A servomechanism responsive to angular orientation of the drum produces a linear scan during rotation of the drum. An optical system within the head provides a common path through a common objective lens for both a write laser beam and for a focus laser beam of an automatic focusing apparatus which positions the objective lens rapidly by a dither motion to compensate for undulations in the surface of the print medium. The objective lens is carried at a reference position during passage of the clamp, the reference position being updated periodically by measurements of focus.

摘要： Drum scanning system to increase the processing speed for scanning/plotting. At each point of the beam travel path, the light beam (18) is rapidly deflected at a predetermined series of angles by an Acousto-optical modulator AOM (10) so that multiple pixels (p1-pn) are struck at the target (26). The duty cycle is increased and orthogonality distortions eliminated.

摘要： In a print head (10) that has a plurality of inline light beams (14) for simultaneously writing a corresponding plurality of lines of an image on a photoreceptor surface (21), the imaged spot size and center-to-center spacing are independently settable by projecting the light beams onto a diffusion screen (15) which is spaced from the light sources by an amount needed to achieve a desired spot size. The spots on the diffusion screen are then imaged onto the photoreceptor surface (21) by imaging optics with a desired magnification to achieve a desired center-to-center spacing (d) between spots on the photoreceptor surface. For a given magnification value the photoreceptor spot size can be set by the spacing between the light source and the diffusion screen independent of the center-to-center spacing between the spots.
