Abstract:
An improved laser scanning system is provided employing multiple off-center lasers and an irregular multi-sided scanning polygon, producing a laser scanning raster over a total sweep of approximately 180 degrees of polygon rotation (i.e. sweep), wherein the scanning region includes (i) a center scanning region with a first plurality of scanning lines, (ii) two mid scanning regions with a second plurality of scanning lines, and (iii) far left and right scanning regions each having a third plurality of scanning lines, to supports high (full) density, mid (⅔) density, and low (⅓) density scanning over the 180 degrees scanning region, for robust omni-directional scanning performance.
