    Abstract: A technique is described herein for using an optical scanning system to visit points in a field along a scanning path. The scanning path includes consecutive passes, corresponding to time-shifted instances of a same scan pattern. The plural passes visit different sets of points within the field, to provide different respective sparse traversals of the field. When motion occurs, the passes evenly distribute the deleterious effects of motion over the field. This produces motion artifacts that resemble blur. The human eye and image processing systems can more effectively handle the presence of blur compared to the kind of motion artifacts produced by a traditional single-pass scanning operation.
