Abstract: A beam position sensor for a beam scanner is disclosed for use in a laser printer. The printer comprises three diode lasers each of which emits at a different wavelength. The beams from the three lasers are combined by the use of dichroic plates to form one combined beam. The combined beam is scanned onto a receiving medium by a polygon. The beam position sensor of the present invention is adapted to sense the position of the polygon in order to provide a synchronizing signal which will insure that each raster line in the printer is started at the proper position. The beam position sensor includes a diode laser and optics for projecting a beam from the laser onto the polygon. The beam is reflected back from the polygon into a photodetector which effects the start of a new raster line at the appropriate time.

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: A modulated writing light beam (18) having a wavelength to which an imaging element (33) is sensitive and a reference light beam (46) having a wavelength to which the imaging element (33) is insensitive are generated and simultaneously directed to a moving optical device (22) to cause the writing light beam (18) to scan across the surface of the imaging element (33) in a first scanning direction (C) and the reference light beam (46) to scan across the surface of a light detecting element (50) in the first scanning direction (C) to generate signals indicative of the position of the writing light beam (18) on the surface of the imaging element (33). The writing light beam (18) is modulated and the imaging element (33) is moved in a second scanning direction (B) in response to the signals generated by the light detecting element (50). Thereafter the exposed imaging element (33) is processed to prepare a lithographic printing plate. The invention is applicable to both positive and negative imaging working systems.

Abstract: An image reading system including a charge storing type image sensor drives a manuscript or an image sensor (1) in accordance with a driving pulse from a driving unit (2). A speed of the driving pulse from the driving unit is determined by a speed setting unit (5), depending on a change of a period of the apparatus scan. The driving pulse is stopped for a certain period of time, so that the difference in a speed of the driving pulse between the different apparatus scan periods is decreased.

Abstract: A photosensor (20a) has a pair of n-type semiconductor layers (21U, 21D) formed on the major surface of a p-type semiconductor substrate (31). A light-shielding pattern (24) comprised of unit light-shielding layers (33) is formed on the major surface of the substrate. When the major surface is scanned by a light beam in the direction (D X ) in which the unit light-shielding layers are aligned, a couple of photo-conversion signals indicating a current position of the light beam on the photosensor are generated in the photosensor. Since the light-shielding pattern is directly provided on the sensor body, no grating glass is required other than the photosensor.

Abstract: Apparatus for reading out individual x-ray images recorded on a double-emulsion radiographic film or on separate films that were coincident when exposed simultaneously to a polyenergetic or broad x-ray photon energy spectrum beam emergent from a body and where an image corresponding to one obtained with a low energy part of the spectrum is formed on one film and an Image corresponding to a higher energy part of the spectrum is formed on the other. One readout apparatus ia for the case of two separate films which, after development, are illuminated from the back and optically scanned to derive analog signals representative of the intensities of spatially corresponding picture elements on each film. Another apparatus is for the case where the two images are on opposite sides of a film and are represented by alternate fine image information lines obtained by interposing a grid during the x-ray exposure. Another is for the case where a reflective layer is disposed between the film images during readout. In all cases the films are optically scanned and the resulting analog signals are digitized and variously processed to yield an image representative of that which is different between the two original different energy images.
