Abstract
A system and method for reading an optical code is provided. The optical code reader system includes a dual aim/illumination assembly including a single light source generating: a) light having a first intensity for providing an aim pattern visible to a user for aiming the aim pattern at a target during an aim period of a scan cycle having at least an aim period and an exposure period; and b) light having a second intensity greater than the first intensity for providing illumination during the exposure period of the scan cycle. An imager module having an array of photo sensors senses incident light and generating image signals corresponding to the sensing during the exposure period.
