Abstract

The simple laser scan pattern having 3 directions and 10 scan lines is designed by computer simulation to increase bar-code readability and to simplify the scanner optics. This scan pattern is generated by holographic scanner including multi-direction scanning. By applying this method,the shallow type point-of-sale(POS) bar-code reader having 160mm height of the equipment has been produced.
