ABSTRACT:
A height- or width-modulated bar code is decoded by scanning an oblong laser beam across the bar code. Light reflected from the bar code varies in intensity as the laser beam traverses dark and light regions of the bar code. The bar code can be decoded by locating the valleys in the variation of intensity of the reflected light, and comparing the depth of these valleys; the deepest valleys correspond to tall or wide bars and the remainder correspond to short or narrow bars.
