ABSTRACT:
A self-adjusting adaptive scanning system includes a scanner, responsive to coordinate control signals, for directing a light beam in a pattern at a bar code symbol, for detecting a reflected portion of the light beam, and for generating feedback signals reflecting successful decodes. A microprocessor, responsive to the feedback signals, generates pattern control signals. A pattern generator generates the coordinate control signals in response to the pattern control signals to select a desirable light beam pattern.
