Abstract

A presentation imaging system used for imaging machine readable information on an object is provided. The system includes a proximity sensor and an imaging device coupled to a processor. The sensor senses the presence of an object within a field of view. A light source projects a structured beam at a first intensity to define an imaging area generally co-extensive with the field of view. Upon detection of the object, the processor signals the light source to project the beam at a second, higher intensity for imaging.
