ABSTRACT:
A graphical code reading apparatus is disclosed. The graphical code reading apparatus is able to read graphical codes on reflective and curved reflective surfaces. The graphical code reading apparatus includes a graphical code reader having an illumination source such as LEDs and a detector such as an imager. The graphical code reading apparatus also includes a light scattering chamber that is coupled to the graphical code reader. The light scattering chamber may have two openings, namely a first opening for receiving the graphical code reader and a second opening for placement adjacent the graphical code. The light scattering chamber may be tapered from the first opening toward the second opening. An interior surface of the light scattering chamber is capable of scattering light because it may be an irregularly uneven reflective surface. The light impinges the reflective surface at multiple angles of incidence upon exiting the light scattering chamber. The light scattering chamber may further be configured with a transmissive diffuser insert.
