description An image acquisition system for identifying signs on mailpieces wherein each mailpiece is moved by being nipped between a conveyor and a housing wall that is provided with a longitudinal slot, comprises, inside the housing, an illumination module having two lighting units that are symmetrical about the slot for the purpose of illuminating a surface defined by the slot, and a camera for forming an image of said illuminated surface, polarization optical means also being disposed between said illumination module and said illuminated surface, and a polarization optical filter being disposed between said camera and said surface. The slot is closed by a flush transparent rigid wall against which each mailpiece is pressed.
