Abstract

See full text

A 2D bar code reader with improved motion tolerance is presented. The 2D bar code reader includes a lens configuration that enhances chromatic aberration to separate the focal planes on which bar code images from two different color components of a light will be focused. An imager interprets one of the focal planes as the image and the other one as noise to be ignored. In addition, the increased depth of field generated by the chromatic aberration allows for a larger aperture stop setting and quicker shutter speed, thereby improving motion tolerance.
