ABSTRACT:
An illumination system and method for use in a handheld symbology reader that employs a grid of reflecting elements applied to a transparent plate adapted to project a highly diffuse and uniform illumination on a subject. The grid defines a geometry with a large number of transparent spaces between grid elements through which an image of the subject can be acquired. A light source array is configured to project light into the grid at a right angle via a light pipe having a distal beveled edge or side projecting light sources. Another light source may be employed to illuminate second light pipe with a chamfered edge to create low-angle illumination.
