Abstract
An apparatus and a method for reading an optical code has a casing with a reading window. The casing includes an illumination device acting through the reading window on an optical code to be read, a detection device responsive to light scattered from the illuminated optical code into the casing through the reading window, and an objective lens interposed between the reading window and the detection device, in a position to pick up the light scattered from the illuminated optical code and project this light onto the detection device. The detection device has a plurality of light-sensitive elements effective to convert the light to electric signals representing the light image, wherein the illumination device has a first array of light sources active in a first illumination configuration, and at least a second array of light sources active in at least a second illumination configuration different from the first one.
