Abstract
This relates to a system for sensing the presence of an object in the field of view of an imaging assembly of a stationary position optical reader. The system includes a light source disposed in a field of view of the imaging assembly, which is configured to emit light in the direction of the imaging assembly according to a predetermined light pattern. A determination as to whether an object is present in a presentation area of the reader system is made by detecting for the presence of the light pattern in image information generated by the imaging assembly.
