OPTISCHE ANORDNUNG ZUM ERZEUGEN EINES ABTASTMUSTERS, WELCHE ZUSAETZLICHE ABTASTLINIEN FUER EINEN LASERABTASTER BEWIRKT

摘要

A laser scanner produces generally parallel scan lines at a target by moving, by dithering, rotating, translating, or wobbling a secondary mirror 51B, 132, optical device, or primary optical element in an optical arrangement which redirects a laser light beam to generate a scan pattern. The laser scanner typically includes an optical device 36 or primary optical element which receives and reflects laser light beams from a laser light source, and a multiplicity of secondary mirrors 51 disposed in positions relative to one another. One or more of the secondary mirrors 51B are mounted and dithered or continuously rotated to generate the scan lines. Other optical elements, such as a primary optical element or device may be rotated, dithered or wobbled in their mountings to produce the scan lines. <IMAGE>
