Abstract
Apparatus for reading bar code symbols including a laser light source, an optical component for scanning a reference plane, and a sensor for detecting the light of variable intensity reflected from the target. A processor determines whether the reflected light represents a spatial variation that could represent a bar code and generates an enabling signal and a controller is provided for modifying the light beam in response to the enabling signal.
