Abstract :
The principle of the design of a new kind of combined polygon scanner for bar code identification is proposed. Prototype of the instrument was put in experiment. The results show that for a bar code carrier at speed of 2m/s within a space of 400×400×600mm and working distance of 1m, the scanner works very well
