10 January 1977 Generating Multi-Dimensional Scan Using A Single Rotating Component
Author Affiliations +
Laser scanning of linear bar codes with random orientation has required the development of multi-dimensional scan generators. Scan patterns of substantial complexity have been generated by single rotating multi-faceted mirrors which had previously been used largely for generating single line repetitive raster scans. Several approaches will be described, including an approach whereby scan vectors generated by the rotating element are reimaged by a second reflection from the element itself.
