MACHINE-READABLE SYMBOL READER AND METHOD EMPLOYING AN ULTRACOMPACT LIGHT CONCENTRATOR WITH ADAPTIVE FIELD OF VIEW

摘要

An optoelectronic reader for reading machine-readable symbol such as barcode symbols employs a detection subsystem having an RX concentrator. The detection subsystem may include an N-tuple RX concentrator. The RX concentrator may define an optical path for light to illuminate the machine-readable symbol.
