Paper Abstract

The needs which should be met in bar code scanning of all kinds of scanners are described. The size of the spot, the depth of focus, the scanning velocity, the data rate of signals and how many effective sans there should be in omni- directional scanning are also analyzed. The formula dealed with or deduced are of advantage to designs of bar code laser scanners.
