Abstract
A process of detecting bar codes constituted by bars having a height H and a width D and presenting flaws of a height A, which comprises the steps of summing the signals issuing from detectors of identical rank which belong to at least two rows of N detectors having a spacing pitch smaller than or equal to D/2, said rows being perpendicular to said codes so that at least one of the distances between said rows is greater than A, and comparing the sum signal thus obtained to a decision threshold to obtain a 'code present' or 'code absent' signal while eliminating any flaws possibly present in said codes.
