The present disclosure provides a method of scanning barcodes located on any side of a product and in any orientation that are moving through a scan volume. The disclosure a preferred embodiment is directed to a method of reading optical symbols using a high speed raster laser beam and non-retrodirective collection optics including the steps of generating a pattern of virtual scan lines traversing a two-dimensional imaging region, the pattern of virtual scan lines having less than the entirety of said two-dimensional region; obtaining a stream of raster data over the two-dimensional imaging region; prior to storing any of the raster data, identifying a select portion of the raster data corresponding to the virtual scan lines; storing the select portion of raster data; and decoding the select portion of raster data.
