Abstract:
1. An apparatus for decoding barcodes, the apparatus comprising: an imager housing comprising a body and a viewing window formed in an exterior portion of the body, the viewing window configured to allow light to travel between an interior and an exterior of the imager housing; a light source, coupled to the imager housing, that emits light comprising a plurality of frequency components, wherein a first frequency of the light is a blue component of the light and a second frequency of the light is a yellow component of the light; an optical system that is located inside the imager housing, comprising: a processor, attached to the imager housing and communicatively coupled to the image sensor, the processor configured to decode the first image formed on the image sensor and interpret the second image as noise, wherein the optical system and the viewing window are arranged such that, when the shutter opens, light is able to travel from the exterior of the imager housing to the interior of the imager housing by passing through the viewing window, through the aperture, through the lens module where it is refracted and dispersed due to the chromatic aberration, and onto the image sensor where it forms an image.
