Abstract:
A system for scanning an imaging plate (10), including a continuous belt drive(36), a drive assembly (40) connected to the continuous belt drive (36), a scanning head (35) connected to the drive assembly (40), and a laser (50) positioned to direct a laser beam (51) in a beam path across the surface of the imaging plate (10), wherein the drive assembly (40) is adapted to move the scanning head (35) back and forth in a path which is collinear with the beam path as the continuous belt drive (36) is rotated in one direction.
Abstract:
Verfahren zur Sanneransteuerung in mindestens einer Scanachse in einem Laser-Scanning-Mikroskop, wobei das Scanfeld in Teilbereiche unterteilt wird, wobei ein von einem Hinscan erzeugtes erstes Bild eines Teilbereiches mit einem von einem Rückscan erzeugten zweiten Bild des Teilbereiches verglichen wird und aus der Abweichung zwischen erstem und zweiten Bild ein Korrekturwert für die Scanneransteuerung bestimmt wird.
Abstract:
In order to record information on a recording substrate (2), a printing head (1) with a number (a) of printing elements (11) is moved to and fro across printing positions (22, 23, 24) by lines. Partial numbers (n) of the printing elements (11) form sub-groups (15) in accordance with a predetermined individual print line which are allocated to the printing positions (22, 23, 24) of a printed line (29) and formed by at least partly differing printing elements (11). The printing elements (11-1 to 11-4) of the sub-group (15) concerned are selectively controlled at the printing positions (22, 23, 24) in accordance with the printing data to produce a model print line (31). On the completion of a subsequent model print line (33), the formation of a subsequent model print line (34) is determined at least on the continuation side on the formation of the previous print line (29). Stripes caused by line continuation errors or inking ribbon structural errors are distributed with a vertical displacement over the printed image by the process of the invention; unlike the case with uniform structures, the human eye hardly takes notice of such distributed faults.
Abstract:
PURPOSE: A method and an apparatus for removing show-through in a scanned image are provided to remove show-through of an image obtained by the difference of show-through of two images obtained by a scanning sensor unit, thereby efficiently removing or reducing show-through effects of a medium in an image scanner. CONSTITUTION: A scanning unit(110) scans one or more lines of a medium(160) at luminous intensity with at least 2. A light driving unit(120) applies light to a scanning area of the medium. A scanning sensor unit(130) senses the light reflected from the medium. A controller(140) removes show-through of an image obtained by the difference between show-through of two images obtained by the scanning sensor unit.
