Abstract
A stationary optical scanning system for the decoding of a plurality of optically readable information bearing symbols encoded using at least first and second different optical codes, and for the detection of a plurality of optical targets having at least first and second different target configurations and target data signals representative of the differing target configurations, includes a single optical sensor for optically sensing the different target configurations and optical codes as objects affixed with the information bearing symbols continuously pass within a field of view and for generating the target data signals from the sensed field of view. A first target processor receives the target data signals and detects the first target configuration in accordance with the target data signals to provide a first processor detection signal, and a second target processor separate from the first target processor receives the target data signals and detects the second target configuration in accordance with the target data signals to provide a second processor detection signal. A decoder receives the first and second target processor detection signals and selectively decodes the inf…
