摘要 |
The invention relates to an apparatus and a method for reading an optical code. The apparatus having a casing with a reading window; the casing having an illuminator acting through the reading window on an optical code to be read, a detector 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 detector, in a position to pick up the light scattered from the illuminated optical code and project this light onto the detector. The detector having a plurality of light-sensitive elements effective to convert the light to electric signals representing the light image. The apparatus is characterized in that the illuminator 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.</PTEXT>
