Abstract
A light source and a light detector are included in an optical reader such as a field of view reader or a flying spot scanner for reading a printed indicia such as a bar code symbol. At least two channels associated with the detector carry signals corresponding to light detected by the detector at different resolution levels, allowing a single reader to be used for different resolution levels of the indicia to be read.
