摘要： A method and system for compensating for scanner facet height error in a laser imaging application including a rotating polygon for directing a laser beam across a dimension of a photographic element. The present invention compensates for facet height error by measuring a scan interval for each facet of the rotating polygon and modifies the pixel clock for a subset of pixels of each scan line as a function of variations in scan intervals for the respective facets of the rotating polygon.Several advantages of the present invention have been illustrated including the low cost of such a compensation system and technique. Furthermore, the present invention is not limited in accuracy by the pixel clock as are conventional techniques. Furthermore, the modified pixels are evenly distributed over the entire length of the facet's corresponding scan line.
