Abstract
An imaging and an illuminating engine is provided for an optical code reader to image and illuminate remote target indicia. The engine includes an image sensor for receiving reflected illumination from the remote indicia and at least two illumination assemblies for providing illumination of the remote indicia. Each illumination assembly is capable of providing a number of different outputs, such as light having different wavelengths or different output durations. A transmissive, optical element overlays the engine for preventing light generated by the at least two illumination assemblies from reflecting back towards the image sensor. The imaging engine is an integrated circuit package for easily inserted and interfacing within an optical code reader as a plug-and-play component.
