Abstract:
An optical reader comprises: a first illumination source for projecting a first illumination field on a target; a second illumination source for projecting a second illumination field on a target; an image sensor array for converting light from a target into output signals representative thereof; and, a processor for decoding information from information bearing indicia within the target derived from the output signals; and, wherein the illuminance of the first illumination field on the target at a distance D from the first illumination source is greater than the illuminance of the second illumination field on the target at the distance D from the second illumination source.
