DEVICE FOR READING FLUORESCENT BAR CODES WITH PREDETECTION OF INTENSITY

摘要

A device for reading a code in the form of a fluorescent mark on the surface of an item of mail comprises in a housing (23) an image acquisition device including a camera (29) with a lighting system (25) for forming an image of an item of mail through a window (24) formed in a wall of the housing (23). The reading device furthermore comprises a luminous intensity pre-detection system (4) able to provide a signal representative of the luminous intensity emitted by a fluorescent mark pre-detected on the item, and a control unit (31) which slaves said acquisition system to said pre-detection signal.
