Abstract
Systems and methods of reading machine-readable symbols are provided. A method of reading a machine-readable symbol includes emitting by a first source outgoing electromagnetic energy comprising wavelengths in a first portion of the electromagnetic spectrum towards a target comprising the machine-readable symbol. Incoming electromagnetic energy comprising wavelengths in a second portion of the electromagnetic spectrum reflected or emitted by the machine-readable symbol are discerned by a global shutter sensor after transmission through at least a first portion of a color filter array having a plurality of portions.
