Date Dec. 10, 1992A laser beam scanning apparatus employs a movable reflector (32) having a large number of flat reflective sides (44) a deflector (16) which shifts the laser beam (10) at high speed across a plurality of the reflective sides (44). The movement of reflector (32) is synchronized with the deflection of the laser beam (10) to produce a desired scan pattern in a first scan direction (X). The reflective sides (44) of the movable reflector (32) may be angled relative to each other in a second direction (Y) to produce different scan lines thereby providing an X-Y scan pattern. The combined high speed beam deflection and motion of the reflector (32) provide scanning of the beam (10) in parallel scan segments thereby providing high scanning speed of the beam with a high degree of resolution.

Abstract: A cylindrical engraving system selectively able to engrave either in a helical or circumferential format. An encoder (22) scans index markings on the surface of a cylinder being engraved and generates timing pulses for selective application to one or the other of a helical drive unit (34) or a circumferential drive unit (32) incorporated within the system controller (30). Engraving is performed by an engraving head (14) which is stepped in the axial direction along the workpiece in response to step pulses generated by the selected drive unit. The step pulses may be generated in spaced bursts or at a regular frequency depending upon whether circumferential or helical driving has been selected.

Abstract: A photographic film printer that forms an image on film based upon received or stored digital information is provided. While maintained in a stationary position, the film is exposed in a sequence of raster scans by a rotating disk traversing the photographic film surface. At least one optical film is attached to the rotating disk in a manner that transmits optical energy directed towards the center of the disk to a peripheral location on the disk. Exposure of the film occurs by controlling the emission of optical energy by the fiber in accordance with the received or stored digital information as the peripheral edge of the disk rotates past the film surface.

Abstract: An engraving system and method for engraving a pattern (Figure 1) using a plurality of engraving devices (34 and 36). The apparatus and method are for sequencing and engraving of the plurality of engraving devices (34 and 36) such that the areas engraved by those heads (34 and 36) meet to provide a continuous engraved pattern (Figure 4b). The system and method (Figure 1) also include an imaging system (22) for imaging the engraved areas associated with each engraving head (34 or 36) so that the heads (34 and 36) or signals (from head driver 62) driving the heads (34 and 36) may be adjusted to further facilitate providing engraved areas which appear as if they had been engraved by a single engraving head when, for example, the engraved area of one head (34 or 36) meets the engraved area of another head (34 or 36). Also disclosed is a method for sequencing and transmitting image data associated with an image to be engraved in order to accomodate any cylindrical offset or the angular displacement between, for example, two engraving heads (34 and 36) that are positioned in a generally opposed relationship.

Abstract: An error detection apparatus and method for use with engravers (figure 9), such as gravure engravers. An error value E corresponding to the difference between a set of predetermined setup parameters and actual measurement of a portion of an engraved area on the cylinder (10') is determined. The error value E is then used to adjust the engraver to engrave an actual cut or etch in accordance with the set of predetermined setup parameters. Advantageously, an error detection and correction system is suitable for providing a closed-loop system for engraving a cylinder (10'). The apparatus and method (figure 9) may be used during initial setup or during normal operation of the engraver. Other features include an autofocus routine (figure 13) to facilitate the autofocus procedure. Also, image processing is further enhanced by gap filling, discontinuity removal, and light calibration methods which may be used alone, in combination with each other, or in combination with the automatic focus system (46') and/or automatic shoe system (209').

Abstract: A system for precisely positioning a printing element relative to a rotating drum, as in a drum printer, employs two position signals for alignment purposes. A pair of linear grids is disposed along a path of travel of the printing element for generating, with the aid of optical beam and sensor devices, a periodic electric signal which varies in accordance with printing element position. One of the grids is stationary and the second of the grids moves with a carriage supporting the printing element. An encoder positioned alongside the drum is operative with a set of markings having a variation in spatial frequency, or a grid overlay, to produce an alternating electric signal which varies in accordance with rotational position of the drum. Motors which rotate the drum as well as a lead screw which translates the printing element may be constructed as synchronous motors to permit phase locking to each other. Circuitry responsive to periodic signals outputted by the linear grids and the encoder introduce phase shift between motor drive signals to align position of the printing element with position of the drum independently of any backlash which may be present between the lead screw and the carriage driven by the lead screw.

Abstract: An improved laser pattern generation apparatus. The improved pattern generation apparatus of the present invention uses a laser beam (501) to expose a radiant sensitive film on the workpiece (516) to print circuit patterns on a substrate. The laser beam is aligned using a beam steering means. The laser beam (501) is split into 32 beams to create a brush. The brush scans the workpiece (516) through use of a rotating polygonal mirror (510). Each beam of the brush may have one of seventeen intensity values. The beams are modulated by an Acousto-Optical Modulator (506) signals provided to the Acousto-Optical Modulator (506) define the pattern to be generated. The signals are created by a rasterizer (507) increased print speed is accomplished through the use of a wider brush and a print strategy that eliminates physical stage passes.

Abstract: A scanning system, having a fixed platen and optical imaging system and a translated reference scale, is provided for scanning of a modulated light beam (or a set of parallel, independently modulated light beams) onto an object surface. The optical system provides a combined light beam including the modulated light beam and a reference light beam. An optical imaging device moves the combined light beam along a scan line, and a translatably mounted beam splitter splits the combined light beam to direct at least some of the reference light beam onto a reference scale and a sensor. The reference scale sensor, which is rigidly attached to the beam splitter, and is responsive to reference beam position in two directions, provides a clocking signal indicative of beam position along the scan line and a vernier position signal indicative of beam position in a direction transverse to the scan line. An optical stepper controls the translation of the beam splitter such as to position precisely each of a series of scans in a direction transverse to the scan lines.
