Alexander R Roustaei, Roland L Lawrence, Ali Lebaschi, Long Xiang Bian, Donald Fisher: Optical scanner for reading and decoding one- and-two-dimensional symbologies at variable depths of field including memory efficient high speed image processing means and high accuracy image analysis means. Symbol Technologies, Brown Martin Haller & McClain, May 26, 1998: US05756981 (568 worldwide citation)

An optical device for reading one- and two-dimensional symbologies at variable depths of field. The device has a light source for projecting emitted light toward the symbol image to be reflected back to an optical assembly, or zoom lens. The zoom gives multiple field of view capability to a CCD dete ...
